    CYBLE-222014-01 and UART to External MCU

    LorenzoDimagiba

      Hi All,

       

      I've been able to power up my bluetooth module and see it advertising from my phone.

       

      I've also been able to capture events transmitted from the module to my external MCU via UART.

       

      Now, I am trying to write commands to the module... I do not seem to be getting the appropriate responses however. I just seem to be getting an echo back of whatever I send. eg. /ping will return to me /ping. I am terminating all the commands I try with '\r'.

       

      I was thinking perhaps it has to do with this deep sleep mode mentioned in section 3.1.5.5 of the EZ-Serial User Guide. However, I imagine if the unit was truly in deep sleep, it wouldn't respond anything to my commands? In the guide I can't see anything about this behaviour, has anyone any experience with it?
