I'm using a pair of XBee PRO 900HP 200K device with the XBee USB adapter.
I'm seeing a reliability problem with transparent mode and trying to communicate from one Xbee to another XBee at 9600.
It seems like more than 50% of the time I cannot get the this mode to work. Sometimes, the XBee's don't see each other at all. Sometimes, the communication is bursty, some characters are transmitted and some are not. All of this is observed in the Console of the latest XCTU tool. I've upgraded the fw on both XBee's. The unreliablity is still there. Is it possible that powering all of this via my laptop's USB is the issue? Has any one else faced something similar and found a solution.
