Can't send bluetooth packet from my custom app

[bbadrignans]

My app can't send Bluetooth packets when a LVGL button is pressed. Worked fine last year.

I checked with Wireshark : I can see packets from Music app buttons, but not from my app.
My app is mostly based on Music app, except it uses also MotorController (I tried also without MotorContoller, same result).
I triple check that my last merge in Infinitime main branch is ok (reduce to just 2 commits).
I also tried this commit without success : #2070

Does something noticeable changed in bluetooth since last year ?
Any other idea ? I'm stuck with my sealed watch without a debugger.

Ho I just figure out that I forgot to register nimble controller in src/systemtask/SystemTask.cpp
displayApp.Register(&nimbleController.home());

Sorry for the noise, but maybe it may help someone else.
