My company has a product line that generally communicates over a serial link but occasionally we get asked to have Zigbee communications. In the past we have used the Atmel (or Meshnetics) ATZB-24-A2 module with Bitcloud and SerialNet. This allowed us to drop a daughtercard onto our system and communicate over a UART with little knowledge of Zigbee or Atmel products but the ATZB-24-A2 near its end of life (if its not there already).
I'm looking into substituting the ATZB-X0-256-3-0-C into our system but it seems that there is no way for us to communicate with it using AT commands (or some other simple protocol). The closest thing I can find is the ZappSI which requires us to port code to our host microcontroller (not Atmel). This is doable but with such little volume of sales I'd prefer not spend a lot of effort on this. I know I'm basically saying I want Zigbee with little effort but the previous module allowed me to do it. Are there any options that I'm missing that would simplify the migration to the new module?
Also, the latest bitcloud version (3.2) comes with a number of precompiled evaluation tools but they are all in .hex format while the pc bootloader tool requires .srec. Am I missing something?
