    Hi,

    I have been programming mdot using mbed libraries, to read some sensor values and send over to Lora network. Recently, micro usb port fell off from the board. I was just wondering If I could achieve what I was doing with mbed libraries by using just AT commands.

    Thank you

    Regards,

    Using a simple usb to serial adaptor you can connect to the mDot. Then you can drop into the bootloader by pressing a few keys after reset and upload files via YModem transfer and program them this way however I’ve found this transfer method to be unreliable even for small files of around 500 bytes.

    Also, at this time AT Commands do not allow reading any of the mDot I/O.
    If you were using the mDot just to send/receive data, AT Commands would suffice.

    Micheal,

    As Steve indicated above, the current AT command code does not contain a command or set of commands for reading i/o. However, you can modify the AT command code to add a command or commands to support reading i/o or sensors and transferring the data.

    Kind regards,
    Leon
