First boot

After a successful Companion flash, reset the board and confirm it starts.

Steps

  1. Antenna attached.
  2. Tap RST (or power-cycle over USB).
  3. Watch the OLED — firmware draws Loading..., then the node name and a Bluetooth pairing pin when nothing is connected.

Expect

Check Pass when
OLED Activity after RST (not stuck black)
BLE advert Nearby scanner / MeshCore app sees MeshCore- plus an 8-character hex suffix
USB serial Quiet on /dev/ttyACM* for Companion BLE — prefer OLED and BLE, not a chatty banner

Verified on this desk after Companion BLE v1.17.1: board advertised as MeshCore-6137C0F2 (Nordic UART service). USB serial stayed silent.

Default advert name is the first four bytes of the node public key in hex, with prefix MeshCore-. Change it later under Configure.

If BLE never appears, re-check you flashed Companion · Bluetooth, not Repeater — see Troubleshoot.

Next: Configure.
