It’s always nice when you for the first time see the data you have been trying to get across a wireless (Jeenode) link arriving :
The “Hello!” messages are just part of a heartbeat mechanism to make sure the link is actually operating.
The digits are the number of the RFID chip I was trying to read.
So in other words now I have a wireless reader (Jeenode) of RFID cards transmitting it’s ID to a central Jeenode receiver.
We have liftoff!
