I am trying to integrate a few sensors and transfer the data via a dual mode bluetooth. I have ordered a TI CC2564 evaluation board and have a raspberry pi with me. So can anyone clarify me on this, whether I will be able to couple a R-Pi with the CC2564 to run the bluetooth stack and my application to send the data via BLE and BT classic. Bluetopia is a supported stack for CC2564, can I run it on my R-Pi. Is there any other supported BT stack.
Thanks for your time.
Regards Gaurav.
I don't know about Bluetopia, but you can try BlueZ on your R-Pi, I can confirm that it is working (on Debian Wheezy) with USB BT dongle.
BTstack is also working on CC2564 (but I couldn't make it work on R-Pi + USB BT dongle since there is some problem with libusb when using BTstack.

I never used a raspberry pi before and I have a project part of which includes receiving data from a BLE blood pressure device over Bluetooth to a raspberry pi 3. I can pair the device to my raspberry but I have no idea what to do next. I need to be able to receive the measurements in my raspberry please help and thank you in advance.
PS: the device I'm trying to use is very similar to this one:
https://ibb.co/71365k5
Thanks for your answers, I have tried "Gatt" and "Gatttool" but the problem is after pairing the device is meant to send the measurement to its application on an android phone, without it I cannot read the blood measurement characteristic or it just does not exist.
Linux uses BlueZ as a default bluetooth stack. It exposes DBus APIs for implementing software using Bluetooth.
If you don't want to use this API directly, which can sometimes feel a bit low level you have many libraries that wrap it, such as https://github.com/getsenic/gatt-python that also comes with examples.
All other solutions requires replacing the Bluetooth stack on Linux and hence your other existing Bluetooth pairings to the system will stop working.
I'm trying to get the onboard Broadcom bluetooth working in a Buildroot 2017.08 built linux on the Raspberry Pi Zero W. It's not showing me the adapter. Bluetooth USB dongles do work.
Things I've already done:
Added rpi-bt-firmware
Added Bluez-tools and Bluez5-utils
Kernel compiled with all sorts of Bluetooth support
Loaded bluetooth modules: bluetooth, bnep, btbcm, hci_uart
rfkill list (shows no bluetooth devices)
rfkill unblock bluetooth (just in case)
After boot I'm manually starting bluetoothd followed by bluetoothctl.
when I type "power on", "list" or "show" it does not give me any bluetooth controllers.
The hardware is working, on the same system I have Debian Jessie working fine with the bluetooth.
Also, given that USB bluetooth dongles work, I think the kernel is OK too.
What could possibly be the problem here??
Anything I could try to troubleshoot??
Anything I could install or add to make it work??
Anything is welcome at this point! :)
UPDATE
I have it working by running hciattach /dev/ttyAMA0 bcm43xx 921600 flow - at start-up. However, I have barely a clue what's going on here. Proper explanation will count as an answer.
I have also removed console=/dev/ttyAMA0 from the cmdline.txt, not sure though if that was necessary.
hciattach attaches serial HCI devices via UART to Bluez stack https://www.systutorials.com/docs/linux/man/8-hciattach/.
In your case the serial Broadcom HCI adapter is at /dev/ttyAMA0, so the command your run attaches it to Bluez as a bcm43xx HCI adapter.
Its probably done the same in your Debian Jessie setup.
I have done pairing of Intel Edison and pi bluetooth dongle successfully but whenever I try to connect pi from Edison I always get.
Connected Yes
Connected No
I am using bluetoothctl to connect
Try flashing an older version of the firmware. The problem seems to be with the recent update of Edison firmware.
The flashing should be done manually because, as far as I know, the wizard can only install the latest version (if you are using Windows, follow 32bit instruction on Intel website). If you found some easier way using the wizard, please share it. Thanks.
i am trying to connect my raspi with a BT-Headset with the build in bluetooth. it is working with pulseaudio 5.0 and bluez 5.23.
But the thing is it just supports A2DP. i want to use it as a real Headset so i Need HFP. I read that bluez 5 doesnt Support this Profile anymore and with pulseaudio 5 and bluez 5.23 it wont work.
Now i got a bluetoothdongle with my Headset and if i am using the bluetoothdongle instead the buildin Bluetooth it is working. i can record Sound. But i get a better Audio Output with the build in (with dongle it is lagging) . Maybe it is because the dongle uses the hfp Profile directly and therefore the Audio ouput isnt that good anymore.
So i was wondering if this is gonna work with every Bluetoothdongle which supports the HFP/HSP Profile.
And my other question is how does pulseaudio and bluez work together. and how would the BT-dongle would work with pulseaudio together?
Bluez 4 supported hfp and hsp. pulseaudio 5 is backwards compatible so this would be an Option i think. does anyone has tried it?
thanks
I am working with a Raspberry Pi (running Jessie), Bluez, and iBeacons (10 iBeacons). My application (written in Python) sniffs for iBeacons and reports MAC address and RSSI. This is a continuous "sniff". The program can run for hours without any overload; however, after introducing a virtual iBeacon (from an iPhone app), the application seems to "overload" not allowing the application to be able to read the other non-virtual iBeacons forcing me to restart the Pi. Also, the virtual iBeacon is transmitting at MUCH faster rates as compared to the other iBeacons. Regardless, this poses a deployment problem as we cannot afford to have a rogue Bluetooth signal overloading the system.
Is this an issue with Bluez, the USB dongle (Iomega), or something else? Not posting code to the forum- interested in where to start looking for an issue. Not sure where to begin.....
Sorry for the vagueness. Was not sure if the issued was in Linux Bluetooth stack, Raspberry Pi, dongle, or elsewhere.
Switched out the Broadcom dongle with a Cambridge Silicon Radio and have eliminated all errors.
Thanks!
