Test OTA command delivery. V7.x expects JL-wrapped commands. Watch for ears flashing!
Enumerate all services like nRF Connect
Console commands after enumeration:
writeToFFC1([0x01,0x00,0x00,0x00])
enableFFC2Notifications()
Run single diagnostic tests
Send [0x01, 0x00, 0x00, 0x00] without JL wrapper (returns status:2 on V7.x)
Wrap OTA bytes in JL protocol (returns status:0 on V7.x)
Load firmware first, then test sequence. Bear ears should flash!
