Bluetooth, Bluez: No reply to ping over bnepX interface - bluetooth

I have trialed to use Network, NAP profiles on Bluetooth.
On Host, xUbuntu 13.04 I have followed as here.
This Host or XUbuntu machine is behind proxy & runs on virtual machine.
It is installed with Bluetooth version 4.101
On embedded board, ping 173.194.112.211 responds as below:

On embedded board, I issue command: ping -I bnep0 173.194.112.211
This is google IP address by the way :)
After long time, I press Ctrl + c, it gives this:

For sure no one has this IP address.
It did not work...
hcidump -X shows these packets when I ping, not other times.

I wish to access internet On embedded board, over Bluetooth, via xUbuntu's Ethernet's internet connection, NOT Ethernet of embedded board.
Someone please help me to get this working.

I configured bnep0 network interface on xUbuntu 13.04 with local IP address and it workded :)
# ifconfig bnep0 192.168.1.3 up
I also guess that command route also helped.
The ping works, however, there is packet loss...

Bluez blotoothctl scan vs hcitool scan

I'm running bluez 5.50 on a Raspberry Pi (both Buster and Stretch). I have a ble sensor device that advertises data only when a button on the sensor device is pressed. So advertisements are asynchronous and there are no periodic advertisements in between (and all packets are unique, no duplicates). I'm having an issue with Bluez though where once a packet is received, Bluez seems to not report any additional packets from the device for the next approximately 11 seconds (very occasionally the interval is shorter). This is with the bluetoothctl line command tool as well as my own c++ application (based off the bluez client/main.c example). In both cases before starting a scan I clear the scan filter, set transport to le, and set duplicate-data reporting on. Conversely, when running hcitool scan I see all the packets from the sensor (it even seems to be reporting all 3 copies broadcast on the different advertisement channels). So my question is, is there a way to get those missing advertisements through the dbus api, possibly some additional setting somewhere? If not, is the hci api okay to use from c++ and should it do the trick? Any help appreciated, thanks!
Edited per Alex's questions -
Have you tried downloading the latest bluez (5.53) https://git.kernel.org/pub/scm/bluetooth/bluez.git ?
Not yet, just wanted to check and see if this might be something known beforehand.
Are you using hcitool scan or sudo hcitool lescan? If you are running hcitool scan, you are picking up bluetooth classic (not low energy packets). hcitool is a deprecated tool. I've found that sudo hcitool lescan only works with BLE 4.x controllers. The function fails on 5.x controller.
hcitool lescan (under root), and yes, the hardware is a Pi Zero/W and a P3 so BLE 4.x controllers (I assume)
Have you tried running sudo btmon to see all of the HCI communication during scanning?
I have but can't remember exactly what I saw other than it didn't contradict anything else, i.e. missing packets w/ dbus api vs hci
Can you provide code for your use of bluetoothctl, ie:
$bluetoothctl
[bluetooth]# menu scan
[bluetooth]# clear
[bluetooth]# transport le
[bluetooth]# duplicated-data on
[bluetooth]# back
[bluetooth]# scan on
always exactly as you've noted...
Could you also provide the results of hciconfig -a

Below is a scan covering about 20 seconds (editing out all unrelated packets),
where I'm pressing down the button on the sensor about every 2 seconds and then
holding it down for another 2 seconds before letting it up. The first chunk
is from bluetoothctl, the second from "hcidump --raw" (on a second raspberry pi). The first four bytes
in the bluetoothctl packet data is a little endian packet seq number
incremented by the sensor for each new packet. The next byte indicates a
button up/down action. You can see bluetoothctl reported packets numbered 05df,
05e5, 05e9. In the raw dump the seq number is at the end of the top line. There
you can see all packets are in order, reported 1 to 3 times (I assume it is
reporting all advertising channels it catches). All packets are present 05df to
05e9 in the hcidump scan. Lastly is the output from "hcitool lescan --duplicates",
which I'm not really sure how it maps...

Could you also provide the results of hciconfig -a
Handling of duplicate advertising data with the BlueZ D-Bus API is an on-going saga that is complicated by the fact that both the kernel and user-space are involved. The following thread over on the BlueZ developer mailing list probably gives the best insight: https://marc.info/?l=linux-bluetooth&m=158225950522806&w=2
The workaround I have been using with the D-Bus API, when scanning for beacons, is to remove the device once I have the data from it. I don't appear to miss data this way. As I don't connect to the beacons, I don't need to worry about losing the paring data for that device.
As a side note, tools like hciconfig, hcitool, and hcidump were deprecated back in 2017

Wrong payload when using BlueZ stack as peripheral

I tried to follow the steps provided by davidgyoung in this question. Here are the commands I use:
hciconfig hci0 up
hciconfig hci0 noleadv
hcitool -i hci0 cmd 0x08 0x0008 48 45 4c 4c 4f 57 4f 52 4c 44
hciconfig hci0 leadv
Which gives me this output:
LE set advertise enable on hci0 returned status 12
< HCI Command: ogf 0x08, ocf 0x0008, plen 10
48 45 4C 4C 4F 57 4F 52 4C 44
> HCI Event: 0x0e plen 4
01 08 20 12
Note that I can't use the advised command hciconfig hci0 leadv 0 because it will throw the error Warning: unknown command - "0".
However, when I try to read out (e.g. with a hcidump --raw) the payload in the advertised package from another device I'm getting an output like this:
hcitool lescan -- duplicates output snippet (both entries are repeated over and over again, looking at the MAC it should be the same device, though):
00:1A:7D:DA:71:14 mint17-0
00:1A:7D:DA:71:14 (unknown)
matching hcidump --raw output snippet:

I'm using Bluez 5.26 and CSR4.0 dongles.
This is the hciconfig output of the advertisier:

And this is the hciconfig output from the 'scanner':

What did I miss to get it to work?
Update:
Following David's advice I changed the cmd values to
hcitool -i hci0 cmd 0x08 0x0008 10 02 01 1a 0c ff 18 01 48 45 4c 4c 4f 57 4f 52 4c 44
getting this output

but still gibberish payloads (payload portion of the hcidump --raw output)
af:08:0a:02:02:01:02
b7:08:0a:02:02:01:02
be:08:0a:02:02:01:02
...
Update 2:
Following the next advice I tried adding some 00 to the payload:
< HCI Command: ogf 0x08, ocf 0x0008, plen 42
10 02 01 1A 0C FF 18 01 48 45 4C 4C 4F 57 4F 52 4C 44 00 00

So still no joy.
Would it make sense to try a different (maybe older) version of bluez? Or can it be hardware related and I should try to get different Bluetooth dongles?
Update 3:
Tried the same with bluez 5.21 which works for David.
Here's a snippet of the hcidump --raw output

The hostname has changed (tested on the third machine so far), so the output is a bit different but I still don't see 'hello world' anywhere.
At this point any ideas are more than welcome!
Update 4:
Tried a different hardware dongle (IOGEAR GBU521W6 as suggested by David) and this looks very promising now!
When using this advertising config:

I get this hcidump --raw output:

As you can see the payload is almost complete, but the last char is missing. By changing the length attribute to 11 I get the full payload:
hcitool -i hci0 cmd 0x08 0x0008 11 02 01 1a 0c ff 18 01 48 45 4c 4c 4f 57 4f 52 4c 44

So for the future (and different payloads): the required length seems to be the bytes of the payload (without the length attribute) - 17 in this case.
Important: It does not work with bluez 5.26 for me, I'm using bluez 5.21 now.
Two issues:
First, in order to get BlueZ to advertise, the byte sequence you supply must include a valid BLE advertisement header, which is a minimum of 8 bytes. So to advertise "helloworld" you actually need to send:
sudo hcitool -i hci0 cmd 0x08 0x0008 10 02 01 1a 0c ff 18 01 48 45 4c 4c 4f 57 4f 52 4c 44
The first 8 bytes are the header and the next 10 bytes are the string "helloworld" encoded as 8-bit ASCII.
The first 8 bytes can be broken down like this:
10 # Total length of the advertising packet
02 # Number of bytes that follow in first AD structure
01 # Flags AD type
1A # Flags value 0x1A = 000011010
bit 0 (OFF) LE Limited Discoverable Mode
bit 1 (ON) LE General Discoverable Mode
bit 2 (OFF) BR/EDR Not Supported
bit 3 (ON) Simultaneous LE and BR/EDR to Same Device Capable (controller)
bit 4 (ON) Simultaneous LE and BR/EDR to Same Device Capable (Host)
0C # Number of bytes that follow in second (and last) AD structure
FF # Manufacturer specific data AD type
18 01 # Company identifier code (0x0118 == Radius Networks)
Note that this header contains two different length fields that you must adjust if you change the length of the "helloworld" payload. Also, for experimentation purposes, you are welcome to use any two bytes for the company identifier that you want.
Second, you can't see the raw bytes of a detected advertisement with the hcitool lescan command. To see the raw bytes, you have to use this command in combination with the hcidump command. See here for details: https://stackoverflow.com/a/21790504/1461050

iBeacon on Raspberry Pi is configured, but why is it not visible?

I have followed the instructions I have found on the internet for configuring the bluetooth 4 dongle with a Raspberry Pi. I thought it was going ok. Running 'hcitool dev'' shows me the device.
So I then created and ran a script:
#!/bin/bash
sudo hciconfig hci0 up
sudo hciconfig hci0 noleadv
sudo hcitool -i hci0 cmd 0x08 0x0008 1e 02 01 1a 1a ff 4c 00 02 15 e5 9f fc b0 b5 2d 11 e3 a5 e2 08 00 20 0c 9a 66 00 00 00 00 c5 00
sudo hciconfig hci0 leadv 3
Running the above script gave the output:
LE set advertise enable on hci returned status 12
< HCI Command: ogf 0x08, ocf 0x0008, plen 32
1E 02 01 1A 1A FF 4C 00 02 15 E5 9F FC B0 B5 2D 11 E3 A5 E2
08 00 20 0C 9A 66 00 00 00 00 C5 00
> HCI Event: 0x0e plen 4
01 08 20 00
I don't know if the above output indicates success or failure, but I suspect all is not well because I installed Locate iB app from Radius Networks on my iPad and added in the details above for my iBeacon and the app cannot see it.
The details of the iBeacon I entered in the app are:
Proximity UUID = e59ffcb0-b52d-11e3-a5e2-0800200c9a66
Major = 0
Minor = 0
Power = -59
Any help greatly appreciated.

Raspberry iBeacon not detecting

I recently was trying to configure ibeacon on a BLE dongle (cambridge silicon radio) on a raspberry pi.
Reference: http://developer.radiusnetworks.com/2013/10/09/how-to-make-an-ibeacon-out-of-a-raspberry-pi.html
I get this message :
HCI Command: ogf 0x08, ocf 0x0008, plen 44
1E 02 01 1A 1A FF 4C 00 02 15 E2 C5 6D B5 DF FB 48 D2 B0 60
D0 F5 A7 10 96 E0 00 00 00 00 C9 00 00 00 00 00 00 00 00 00
00 00 00 00
> HCI Event: 0x0e plen 4
01 08 20 12
And the app does not even locate the beacon. Though I can see the dongle flashing some light on this command:
sudo hciconfig hci0 leadv 0
But nothing gets detected.
So go an APP named LIGHTBLUE from the appstore and it detects the bluetooth with a different UUID.
I have tried this a number of times now. And have completed all the steps in the tutorial. But this bluetooth device just wont show up.
Also, I am curious to know what is 0x08 and 0x0008
and if I want to cast a different UUID what should I do? But thats a later part...
Right now, THE BLUETOOTH wont cast the Estimote UUID as said by Radius Networks' tutorial.
Hope to receive some reply soon.
Command I wrote (after this not working I changed the power to C9):
$ sudo hcitool -i hci0 cmd 0x08 0x0008 1e 02 01 1a 1a ff 4c 00 02 15 e2 c5 6d b5 df fb 48 d2 b0 60 d0 f5 a7 10 96 e0 00 00 00 00 c5 00 00 00 00 00 00 00 00 00 00 00 00 00
and surprisingly, the error is: Error: Invalid HCI Command Parameters;
How come its invalid?
Is it because CSR supports 128bit rather than 64bit hex?
Thanks!
I saw the same issue as memoryhole where I had to remove the extra zeros.
I also had to enable advertising before I configured the advertising data for it to work properly with my dongle.
Here is the exact sequence/commands that worked for me:
sudo hciconfig hci0 up
sudo hciconfig hci0 leadv 3
sudo hcitool -i hci0 cmd 0x08 0x0008 1e 02 01 1a 1a ff 4c 00 02 15 e2 c5 6d b5 df fb 48 d2 b0 60 d0 f5 a7 10 96 e0 00 00 00 00 c5 00
This is what my version of the Radius script ended up looking like:
#!/bin/sh
. ./ibeacon.conf
echo "Launching virtual iBeacon..."
sudo hciconfig $BLUETOOTH_DEVICE up
sudo hciconfig $BLUETOOTH_DEVICE leadv 3
sudo hcitool -i $BLUETOOTH_DEVICE cmd 0x08 0x0008 1e 02 01 1a 1a ff 4c 00 02 15 $UUID $MAJOR $MINOR $POWER 00
echo "Complete"
This was on a Rasberry Pi with a ORICO BTA-402-BK branded BLE dongle (CSR8510 A10)
(I would have left this as a comment, but didn't have enough rep)
I also have a CSR based USB Dongle bought in Hong Kong. I got the LE Set Advertising Data command to work by removing the extra padding at the end. According to the Bluetooth 4.0 Specification the data field should be 31 octets long. I'm not sure why the Radius Networks tutorial adds the extra zeroes. Try this:
$ sudo hcitool -i hci0 cmd 0x08 0x0008 1e 02 01 1a 1a ff 4c 00 02 15 e2 c5 6d b5 df fb 48 d2 b0 60 d0 f5 a7 10 96 e0 00 00 00 00 c5 00
Note: I didn't run this on a Raspberry Pi, but an Ubuntu 12.04 laptop with bluez-4.98.
I bought a few of these from amazon:
http://www.amazon.de/CSL-Bluetooth-Adapter-Technologie-neuester-Standard/dp/B00C68IQ3C
and did not get it to work in the beginning following the Radius tut. Running hcidump in another window showed an error message when giving the hcitool command:
> HCI Event: Command Complete (0x0e) plen 4
LE Set Advertising Data (0x08|0x0008) ncmd 1
status 0x12
Error: Invalid HCI Command Parameters
After removing the extra 00's at the end of the hcitool command, it worked. My config file is:
export BLUETOOTH_DEVICE=hci0
# E2C56DB5-DFFB-48D2-B060-D0F5A71096E0
# export UUID="e2 c5 6d b5 df fb 48 d2 b0 60 d0 f5 a7 10 96 e0"
export UUID="92 77 83 0A B2 EB 49 0F A1 DD 7F E3 8C 49 2E DE"
export MAJOR="00 00"
export MINOR="00 00"
export POWER="C5 00"
note the extra 00 in POWER! this extra 00 is important.
My beaconstart script is:
#!/bin/sh
. ./ibeacon.conf
echo "Launching virtual iBeacon..."
sudo hciconfig $BLUETOOTH_DEVICE up
sudo hciconfig $BLUETOOTH_DEVICE noleadv
sudo hciconfig hci0 noscan
sudo hciconfig $BLUETOOTH_DEVICE leadv 3
sudo hcitool -i hci0 cmd 0x08 0x0008 1E 02 01 1A 1A FF 4C 00 02 15 $UUID $MAJOR $MINOR $POWER
# sudo hciconfig $BLUETOOTH_DEVICE leadv 3
echo "Complete"
While try-and-erroring I also added the noscan and put the leadv 3 in FRONT of the hcitool command. But only after removing the extra 00s it started to work.
HCI Event: 0x0e plen 4 01 08 20 12
translate into: set advertising data command has finished running with error 0x12 "Invalid HCI Command Parameters"
ogf 0x08, ocf 0x0008 is the command to set the advertising packet's data, so you change the arguments to that command to modify the UUID. You want to change the part of the string of hex that corresponds to the UUID. Notice this:
sudo hcitool -i hci0 cmd 0x08 0x0008 1e 02 01 1a 1a ff 4c 00 02 15
e2 c5 6d b5 df fb 48 d2 b0 60 d0 f5 a7 10 96 e0 00 00 00 00 c5 00 00 00 00 00 00 00 00 00 00 00 00 00
iBeacon broadcasting Profile UUID
E2C56DB5-DFFB-48D2-B060-D0F5A71096E0 with a major of 0 and a minor of 0
Are you sure you have a Bluetooth 4.0 dongle? What's the exact command you typed in? (cut-n-copy it into your question)
Unfortunately, you need a different bluetooth dongle. There have been other reports of the CSR not working with the Bluez stack on the Raspberry Pi for iBeacon advertising. See here and here
I have verified the command you have above does not give an error when using the recommended IOGear GBU521.
I was successful with a Raspberry Pi and a Inateck csr4b5 BT Dongle which should contain CRS 8510. By complying to the BT specs 31 octets length just like memoryhole said and omitting the extra 00 octets at the end it worked.
Edit: Also worked with a Pearl Dongle Model PX-1632-675 and a CSL USB Bluetooth Nano Dongle CSL-Nr. 23996
Give it a try.
Cheers
