How to check if softwareSerial port has finished sending?
hi,
my application uses 2 softwareserial ports. 1 talk esp8266 @ 9600bps , talk device @ 1200bps. latter doesn't support higher speeds. in cases application replicates data packets 1 port other or without pre-processing.
my question how avoid overflow situations in slower serial port considering there no serial buffer on tx. in other words, how can make sure 1 packet has been sent before trying send next?
thanks
