Hi Albert,
thanks a lot for your information. Please note that in my attempt to power on/off XBee via D5 I cut the PCB connection between Vcc and EN and I made the solder blob between EN and CTL_D5. This is the hardware part.
In the code I set pin D5 for OUTPUT and than I tried to switch XBee on/off by digitalWrite(5, HIGH) (or LOW). Unfortunately the program was not able to run. LED D8 lit on for a while and went off shortly and so on again and again …
I also measured the voltage on XBee +3,3V pin no.1 getting arrising voltage up to approx. 2,9V and then dropping down to 0V and again … When I removed XBee from the socket program started and was “looping” as expected. Stalker worked and now, after turning-over the solder bridge back between Vcc-EN, works with attached XBee without any problem.
I have just got from you another Stalker v2 so I will try to do more tests and I’ll let you know.
Cheers
Vladimir
