I’m opening FCM data connection over UART1 to a serial device and for every command sent by fcmSendData, the datahandler will be called to return the response.
For the first six calls to fcmSendData(), a corresponding response is returned by FCM datahandler. But after that, the datahandler was never called.
We probed the comm line and confirmed the data sent by fcmSendData and there’s response data coming in to WMP, but the datahandler never caught that response.
Has anybody seen this problem?
