PC-BLE-DRIVER on FENSTEL EV-BT840F (nRF52840 MCU)

[Bhavesh Shah]

I am successfully able to use pc-ble-driver on nRF52840 Preview DK using latest connectivity firmware loaded by nRF Connect.

I want to use the same functionality on FENSTEL EV-BT840 which have the same controller as nRF52840.

nRF52840 have the connectivity IC on board which is used to connect in nrf-Connect and PC-BLE-DRIVER.

In my understanding the nRF52840 is doing communication with pc-ble-driver on UART which connectivity IC on board. And nrf-connect and pc-ble-driver both able to detect that while opening port.

In EV-BT840 there are UART pins available to access. When I use that pins using TTL to USB converter and try to open the port but i get the following error

"pc_ble_driver_py.exceptions.NordicSemiException: Failed to open. Error code: 13"

Is there anything that I misunderstood or I miss to implement. Any reference to pc-ble-driver implemented on FENSTEL BT840/BT832 chip wlll be very helpful.

Hello i try also to use pc-ble-driver with EV-BT840XE.

Is it necessarry to use a MAX3232 ?

I thaught that to have the good hex file it was needed to use connectivity UART but you use hci ?

Do you have your project or  your code to have an example please ?
