The bluedot library is very good and something I use regularly so I would expect it to work. It is not clear from what you have written that you have the server and client code up and running. Start the server on one RPi, and then start the client on the second. This should take care of the connection for you. If you don't have these running then there is ...

If you want general data exchange between the ItsyBitsy and the RPi, then I would go for the bleuart example. I believe this is the Nordic BLE UART Service. Sometimes called Nordic UART Service (NUS). This is not an officially adopter profile by the Bluetooth SIG, but it is a common custom profile that is documented in a number of places. There are some ...

Answered my own question with help from this link from Mark Hills Once you have bluealsa working and can connect devices and play, then these additional steps open up dmix capability and allow audio mixing. Install loop module once only. modprobe snd-aloop Edit /etc/asound.conf for each bluetooth connection - i.e. if you change device, update this file. ...

Quite often when pairing has happened but there are issues connecting it is because there is a mismatch between the services offered at both ends of the connection. With info you have shown what services are available on the remote device. If you do show then that will let you know what is available on the RPi. I would expect the following to be included on ...

If you have a look in the /boot/overlays/README file you will see that the folk at RPF/RPT have tried to sort this out by actually renaming the file: This overlay has been renamed disable-bt Unfortunately, the internet never keeps up 😢 so you will not find a pi4-disable-bt option. You can continue to use the pi3 command but I would use the disable-bt ...

Finally solved it ! I thought this was an issue and searched how to "fix" it but it is an intended behaviour. 20.04 solution (source [FR]): Install the pi-bluetooth package: sudo apt-get install pi-bluetooth Edit the /boot/firmware/usrcfg.txt file to add the following line at the end: include btcfg.txt Reboot: sudo reboot Check that the device ...

It seems that you have had no response to this so I thought I would have a try to see how far I got. These are my notes from the journey. This was not a successful journey for me but I'm hoping by sharing my failure it will help someone build on it. From searching around it is clear that how to configure Bluetooth Personal Area Networks with BlueZ has ...

Yes the Raspberry Pi can scan and read the data from BLE Beacons. There are lots of different beacon data formats, one of the more popular is the Eddystone format. https://github.com/google/eddystone There are dedicated beacon manufacturers of beacons that will run on coin cells for a year+. If you wanted to create something yourself, then boards like the ...
