custom board with nRF52832, can not connected to NRF CONNECT in PC

[esonhon]

Hi,

I've built a custom board with nRF52832, without other MCU like PCA10040. I use a FT232RL to bridge the USB to nrf UART, flashed nrf5 uart connection firmware ble_connectivity_s132_uart_pca10040. Modified code to actual GPIO connect on the board.

I think I can locally connect my board to pc, and debug via nrf connect just like NRF DONGLE, but failed.

NRF CONNECT find my board and display a serial number, but connect with fail message "Unsupported device with .....", pls check the picture

I have double checked the hardware connection, and other demo runs normal on it.

So, if  JLINK debugger is MUST HAVE to connect with NRF CONNECT?  Or just uart connection is required to send / receive serialized command? Or  there is some communication protocol between NRF CONNECT and other mcu that connected with nrf52(AS PCA10040 NRF52DK)? 

Thanks.

HI Weihe, 

our nRF52840 Dongle  does not have a J-LINK OB and uses a serial connection over USB to communicate with nRF Connect. 

The BLE application in nRF Connect for Desktop relies on the devices having the Nordic vendorID/productID. 

Best regards
