I’m using the adl API (adl_OpenDevice/read/write direct access) to communicate with an external device through the device UART2.
The external device periodically sends data (read operation) and the wavecom modem sends an acknowledge (write operation).
If the external device doesn’t get the acknowledge from the wavecom, it will retry 5 times and stop if no more acknowledge are received.
I notice that sometimes (2 or 3 times per day) the external device stops to send data because the wavecom doesn’t sends answer.
When the problem occurs, It seems that the write operation doesn’t really sends data…
I’ve read the firmware R73a correction:
When write operations are triggered periodically the OnTxComplete event handler is sometimes not recalled. Consequently the pending write operation never ends.”
Where can I find more information about that ?
Does somebody have the same problem ?
