Can anyone give a list of Instructions on how to implement Bonding/Pairing in BLENO? I have created a list of ble profiles but don't know what to code or do in order to implement pairing.
Bleno doesn't really support proper bonding. Use BlueZ instead.

I want to use a bluetoothmodul like this Waveshare Core51822 to send data to a raspberry. I want to use the SPI on the bluetooth modul but i dont have a plan how to configure that.
What do i need?
Thanks
The SPI and BLE are all documented extensively at http://infocenter.nordicsemi.com/, including examples, specifications, and an API.
In the future, you should give much more information about your situation. For instance, what platform/IDE are you using to develop? If your module is compatible, you would probably be best off using ARM's mbed compiler (https://os.mbed.com).
I have this sensors https://lonauto.en.alibaba.com/product/60692809352-806479288/4pcs_Sensor_one_set_intelligent_Tpms_tire_pressure_monitoring_system_free_app_on_iso_android_phone.html?spm=a2700.icbuShop.prewdfa4cf.7.1b29ca9abaaU3n from which I want to get some data over Bluetooth, it's low energy device which isn't discoverable - don't really know how pairing works at all so I need a lot of informations about pairing and everything. Any ideas would be welcome.
They have offcourse official app, but customer want custom app so therefore pairing should be in this custom app.
Bluetooth low energy overview AndroidDeveloperGuide
This guide will help you with creating the logic for connecting and exchanging information from the Sensor.
Please follow all the classes mentioned in the Guide in detail, the various classes' constant variables and methods will give you good knowledge of what sorts of information you can get from the sensor.
I have a Raspberry Pi that acts as a BLE peripheral. I want to add Apple's HomeKit Accessory Protocol (HAP) to the Raspberry Pi's BLE code, to control the BLE device using Homekit. I would like to avoid implementing HAP over the internet.
The closest resource I found is https://gist.github.com/KhaosT/6ff09ba71d306d4c1079. However, this gist makes it seem like there are many unknowns with that process.
Does anyone know if this is possible? If so, any info or resources would be greatly appreciated. Thanks!
As mentioned at https://developer.apple.com/homekit/ under Accessory Developers, you need to first sign up for MFi and then you will get access to all the resources you need in order to implement homekit. All source code you can find publicly online is against Apple's license since they prohibit public redistribution of documentation and source code of implementations.
Is it possible to program a BT beacon to advertise a sequence of different Eddystone-URL/UID's in sequence? I imagine I could from something like a Raspberry Pi3 with a BT adapter, but I was wondering about something like an actual beacon.
Yes, this is possible. This technique is called "interleaving", and it is possible to do with both software beacons and hardware beacons.
Eddystone actually relies on this technique in order to match its multiple frames. When a receiver sees an Eddystone-TLM frame coming from the same device as Eddystone-URL or Eddystone-UID, it knows that the telemetry is for that beacon frame.
Using the same technique, it is possible to send out multiple URL or UID frames from the same device using different identifiers for each frame. Some commercial manufacturers such as Radius Networks support doing this in some of their products.
I dont think so. Im pretty sure you would need to have some smart device nearby that is running a program that is periodically changing the UIDs. The micro-controllers that power these beacons are pretty bare bones and are really optimized for transmitting bluetooth signals.
Here's how to do it.
EddyStone supports four types of payloads/frame-formats i.e, UID, URL, TLM, and EID.
Eddystone UID/EID are the frame-formats to use for this purpose.
As far as using the 'NordicSemiconductor NRF line' of beacons just make sure that these are fully Eddystone compliant i.e, support the EID frame-format.
Freely available Google Beacon Cloud platform is great for trying this out (called 'registering and provisioning your beacon').
It can be implemented w/o building or requiring any custom app at the client end.
On the client-side.
Use 'Google Nearby Notifications' & 'Google Nearby Messages'
On the server/cloud-side.
Google Proximity API for 'registering and provisioning your beacon'
Use 'Google Nearby Messages' API
Good luck with your project .
I'm working with BlueZ 3.x. I have a linux embedded device and I need to send and receive files using the bluetooth technology, with Obex. (Note: BlueZ 4.x doesn't even compile on our specific platform.)
I don't need PIN authentication, I even don't want it. It must remain as simple as possible for the end user.
I tried to set security none in hcid.conf but it doesn't seem to work.
So my question is:
Is it possible to send &/ receive files using Obex on bluetooth?
How to do it?
Does bluetooth devices (e.g. mobile phone) requires authentication?
You can use the OBEX protocoll for that, but you will also need the FTP or OPP profile (And GOEP, SPP & GAP since they depend on them)
The documentation can be found on BT SIG bluetooth.org, but you will have to be a member. I think some of the documentation is available to non members as well, go there and have a look.
Yes (if we are only talking about mobile phones)
