Hi, I have an XBee SMT Grove with XBee S2D. First of all, XCTU recognize the radio module only if I put the grove in loopback thorugh P11 header. Even then the module is recognized as 705B and I cannot update firmware! Any suggestion?

Sounds like an issue with the grove board. I would suggest getting an XBIB-CU-SMT board to work with.
