HCI_UART | three wire (TX, RX, GND) | Solution

Aim: interface nrf32852 with i.MX6UL based Linux board through UART and configure hci of bluez.

Board: nrf52_pca10040
SOM :  nRf32852
OS:    Zephyr

UART: we followed HCI_UART example.

1. We could interface with UART H4 five wire (TX, RX, RTS, CTS, GND). and we were able to scan BT devices.

2. we wish to do with three wire (TX, RX, GND). Please suggest process and example.

  • Hi Simon,

    we could fix booting (application start) problem with below set of commands.

    Commands:

    make -GNinja -DBOARD=nrf52_pca10040 .. -B .
    ninja
    nrfjprog --eraseall nrf52
    nrfjprog --program zephyr/zephye.hex
    nrfjprog --reset nrf52 

    Please note 'ninja flash' didn't work for us.

    now we are starting our UART HCI task. shall update you if any.

    Thanks,

    Ronak
