we currently have problems in reading the configuration from S2C modules with XCTU - by using the SparkFun XBee Explorer USB.
We have seen under the following link
that S2C modules have to be prepared by programming with boot loader to receive/see configuration within XCTU. Is that really necessary?
We have bought brand new modules like always and we never had to program such modules before.
Normally XCTU instantly detects the modules after pluging.
