Good evening,

Who has tested the CM5 with modules xBee of MaxStream.

At the moment when the data are not sent wholesale volume this works perfectly ...

But for downloading and file for use with URBI this problem. I think this is a problem of settings ...

Mince the problem is that the XBEE it's CMOS-LOGIC (3.3V) and that it's CM5 TTL-LOGIC (5V).

Too bad ... However orders for short this seems to work well.

Actually near the Zig100 interface on the CM5 there is a 3.3V regulator.
Search on this forum the threads related to hooking up the BlueSmirf to CM5 for more info.

In fact I have connected the xBee at the UART0 ... For now using the RobotTerminal it works perfectly except loading file because it generates a checksum error. So I continue on this track.

You can fix the checksum error by sending the checksum byte immediately after the rest of the data. The checksum is literally the byte-sum of every data byte.

If you're still getting checksum failures (or you're using the Robotis file upload, which does this automatically) then your data is being corrupted.
