Need firmware nrf52840 with REPL over BLE

[patfrench]

Hello,
I have a problem that I can't solve. My nrf52840 device is visible but I get a GATT connection error when I want to connect.
Connexion au GATT server... VM278:56 Erreur de connexion BLE: NetworkError: Connection Error: Connection attempt failed.
I may have built my firmware incorrectly.

does anyone have a firmware that works?

thanks in advance
