Description
The standard examples pair SerialToSerialBT / SerialToSerialBTM fails. Noway to get the link even after reset & Co
The same works pefectly in 2.0.4
SerialToSerialBT in 2.0.4 SerialToSerialBTM in 2.0.4 OK
SerialToSerialBT in 3.2.0 SerialToSerialBTM in 2.0.4 OK
SerialToSerialBT in 2.0.4 SerialToSerialBTM in 3.2.0 fails
SerialToSerialBT 3.2.0 works well with a terminal application on a phone
Sketch
Standard examples from the distribution packageDebug Message
Both examples compiled with debug core debug level "debug":
