I have several XBEE PRO 900HP modules (XBP9B-DMST-002). This is the US version with all of the frequencies enabled. (ATAF = FFFFFFFFFFFFFFFF and ATMF=0x19)
I want to configure them for use in Singapore, but the ATCM is not supported in XCTU (and does’nt work sending AT commands directly either). Even if I could, I think it would violate the ATMF minimum frequencies value (there are only 15 for singapore)
I also don’t see any available firmware to turn this into an XBP9B-DMST-042 variation.
Am I missing something? Do I have to purchase new hardware?
