meshcore bluetooth connection from Linux is not working.

MESHCORE v1.10 firmware
meshcore_py v2.2.1

I have installed meshcore-py on rpi4 and fedora desktop. When trying to connect via bluetooth. The first connection starts fine pairing finishes, then bluez disconnects. using exemple ble_infos script:

First attempt on rpi4 pairing fine and connection started comes back with looping :

Hi, does meshcore-cli works ?

I'm not sure examples are up to date, I've just made the example work on my debian machine though, I'll also test with rpi at home

meshcore-cli -l can be used to scan for devices, meschore-cli -S to scan and connect by selecting the device, if it works with meshcore-cli, then you should be able to make it work with the whole python lib

The kind of error you have (on your second attempt with pi), is the one I usually have when the pairing is not valid anymore ... I usually remove the device using bluetuith (because it's the simplest tool that I found to do that well) and do the pairing manually using bluetoothctl, if using meshcore-cli, you can have bluetoothctl in a terminal and use the -P option when invoking meshcore-cli, it will make bluetoothctl ask you for the pairing pin ...

Run into same issue. I presume it is very likely hitting some edge-case something to do with my node being a lilygo t3-s3. The android/iOS app works as expected. So I will try to pinpoint the issue as I go.

[takov751]

Well this is very likely device specific.
I have installed the bluetooth companion version. Does the bt version couldn't be that different to be unable to connect via script/cli over bt.
I have tried connecting trough serial and this is what happens, which is obvious given i have the bt companion firmware version installed:

[fdlamotte]

Have you changed your firmware to serial companion before connecting through serial ?

[takov751]

No i have not yet. That will be for tomorrow . However does that firmware has the capability to enable bluetooth? Sadly due to node placement i need wireless connection

Update: I have flashed the usb companion firmware, and it does works with the python script and cli tools , however as expected I have lost bluetooth functionality. So I presume I won't be able to use any script or command line tools when bluetooth firmware installed by design @fdlamotte ?

What I don't understand is why it won't work with the pi4/esp32s3 combo, there are sometimes issues but this combo is quite common and should work ... (don't see what would be so special about t3s3)

An alternative to bluetooth companion is using wifi. Both meshcore_py and the android version of the app support it. You'll have to build a custom firmware though and configure ssid and password in platformio.ini. For a remote note it would be a good option ...

There is no target for wifi companion on t3s3 atm, you should copy usb one and add (see how its done for heltec_v3)

  -D WIFI_SSID='"myssid"'
  -D WIFI_PWD='"mypwd"'

then to connect with mccli use meshcli -t <host>

Okay. That is excellent, however I have shot myself in the foot as my main phone is an iPhone 11 🥲 so that i will presume won't work. Anyhow it seems I have stumbled upon an edge-case scenario, which is only a mild annoyance for me. So it is not a bug, just implementation limit. My main goal was to create a matrix appservice( soon™) to work in concert with meshcore node(s). So I am very likely have to move my rpi4 upstairs and connect via usb serial, like a "caveman" 😆.

On the other hand @fdlamotte I am trying to determinate, what does webapp or iOS/android app does differently over BLE? Is there a chance that for some reason in the T3-S3 bluetooth version firmware Serial was not enabled?
