Hi, my setup is based on RAK4631: RAK19007 Base Board - RAK13800 Ethernet Module - RAK19018 PoE module

After mounting and connecting to MACBook via USBC I did factory reset and upgrade with latest Meshtastic beta firmware. I can setup RAK4631 via Web interface and meshtastic CLI. I set also static PIN for bluetooth. Problem is, that I cannot pair RAK4631 via Bluetooth with iPhone App or MacBook. I can see RAK4631 in device list in App, by clicking on it I can see just Connection Attempts with no success. After first attempt I can see that RAK4631 is immediately rebooted. I think it must be hardware problem with RAK4631. I have also tried to use different firmwares with same result.

Welcome to the forum @laci

If the device boots and advertises over BLE then there is no hardware defect.

The BLE connection is for the Meshtastic mobile app only, I don’t think it works with a computer connection like your MacBook.

For BLE to a mobile device, try the Nordic nRF Connect application and check if that can connect to the device.

Hi @beegee , i have tried nRF Connect IOS App, i can see device on bluetooth scan list, If i click to connect, device is immediately rebooted without successful BLE connection. I have also received special firware from rakwireless support: Mesh_Test_V1.1.6.uf2. I can see RAK-TEST-xxxxx device in the list on nRF Connect IOS App, if i click connect, same behaviour, i am immediately disconnected from serial port - device is rebooted.
