CC2541: HM-10 using UART communication

Iddo Lazar

Part Number: CC2541


HI.

I flashed the BLE Bridge firmware on the HM-10 board which I bought and trying to use the UART for communication.

I currently not able to see any signals being sent through the TX when I use the serialinterface sendDataToHost function.

Does any one know which configurations I should change (if any?) regarding the UART port or any other specific board configurations to make this work?

Thanks!

    HI Iddo,

    Which BLE Stack are you using and what example? Can you list the steps you have taken to enable UART?

    Cheers,
    Fredrik

    Using BLE stack 1.4.2
    using BLE_Bridge sample

    I have changed the BR to 19200
    implemented a callback function
    tried both UART_PORT_0 and UART_PORT_1 - I think that HM-10 needs port 1

    In case you know of the simplest way to configure UART and the right configuration options for the standard HM-10 or CC41A boards.
    I will really appreciate the help.

    Thanks!
