Send error on xdot

[Martin Pelletier]

Hi,
my system is peer to peer with 3 slaves and 1 master. And if one slave has this error (MDOT_TX_ERROR = -2) after trying to send a message to the master then it will not be able to send again! What can I do in order to send again? =>clear this error? And why i got a send error?

I used this without success:

status = _dot->send(SendVector, false);
if (status == mDot::MDOT_OK) //
{
….
_dot->recv(data);
}
else
{
if (_dot->getSerialClearOnError()) //8dec16
SendVector.clear();
}

Thx for your response!!

Have you analyzed the debug output?
It may be helpful to see the system event log.

Do you have ACK enabled? This would only work with a P2P system between two dots.
The P2P feature was not designed for more that 2 end-points.

This mbed user has some good examples of using the Sx1272 chip on the mDot without the library if you want some lower level control.

Hi Jason,
ACK is not enabled. I have my own Ack. If i got a tx error then the sx1272 stops to send any data but the program still turns. Can i reset the sx1272?

thx for your answer
