On RIcardo Barrera Thank you so much Ayoub. One problem solved, a zillion left to go. My project at this state is to have an autonomous free-roaming robot that uses two Arduinos for motor/stepper controls and sensor reading that pass data to the Beaglebone for analysis, and oversight while the Beaglebone then (wirelessly) passes on significant data to a laptop for recording and possible further analysis.

The plan is to also allow the Beaglebone to step in when necessary and if required to swap sketches on the Arduinos as required by environmental exigencies. I envision using the Beaglebone as the ‘conductor/composer’ and the Arduinos as the ‘orchestra’.

On Anthony Hi, Thanks for your post it is very useful. I can write on TX but I have some troubles when I want to read data on RX. I use exactly your program and on my BeagleBone I connect the Tx pin to the RX pin. So if I understand your program, when I write a data on TX I should see the same on RX and so on the console. But I have no answer on the RX port and when I execute the “in. Hand Maiden Kotor Hot. read(buffer)” function it seems to stop the Reader Thread. Do you have any idea on how to fix my problem?

Thanks for your help.
