Use PC-BLE-DRIVER on FENSTEL EV-BT840XE (nRF52840 MCU)

Piwy

Hello,

 I want to use pc-ble-driver WITH an EV-BT8400XE.

I develop with SDK15.3 (last compatible version of SDK for pc-ble-driver)

I am successfully able to use pc-ble-driver on nRF52840 by using pre-compiled files or by use patch for SDK 415.3 with ble_connectivity\pca10056\ser_s140_usb_hci example.

I think for EV-BT840XE to work with pc-ble-driver i need to use connectivity\ble_connectivity\pca10056\ser_s140_uart example because ev-bt840xe have a bridge USB to UART

 1 ) => Could you confirm that it's the example i need to use or not ?

First of all i don't succed in the use of UART in this board, i tried to use app_uart example with PIN_RX =11 and PIN_TX=12 according to the schematics of the EV-BT840 board, 

I don't understand how to use Uart with EV-840xe and if it's the right way of think to use pc-ble-driver with it ?

Can you help me understand how to configure this board for this use ?

Thanks!

Regards,

Pierre-Yves

    Hi

    I used  nRF52840 on two different custom board,  one with USB directly connect to the nrf52840 (this is the board that i'm succefully able to use pc-ble-driver), one with a UART to USB Bridge FT234XD, it's not the same but it UART works with it and not with the one of the BT840XE (CP2102) event if it's connected the same way, that's why i don't understand...

    The first custom board with USB directly connected works as a dongle and not as the others board, i can't use the same connectivity for the others.

    But if UART works on the board  with the UART to USB Bridge FT234XD, it's strange that it's not working with ev-bt840xe, i think i miss something basic or maybe the bridge isn't compatible , i don't know , do you have any idea about this ?
