I am using a Netduino PLus 2 with s/w 4.2.2 update 2 and have met a strange problem.
I am sending a serial message to a device which responds with a reply of 26 characters.
The default baud rate is 115200 on com2. My software continually sends a message to the device waits for a reply and then sends it again.
After about 10 seconds I get a reply but with 1 or 2 missing characters.
I have tried reducing the baud rate but the same problem occurs.
I have been running with a network cable plugged into the netduino ( my code does not use the network ) but if i remove the network cable the problem improves - at 19200 it will then seem to run for 10's of minutes with no problem.
My question :-
Is there a known problem with serial receive?
Is there a known problem with the network interface interfering with serial receive?
