Modulation and Encoding in Xbee SX Pro

Hi There,

I want to know if the modulation/demodulation and encoding/decoding of the data is software based or hardware based. If it is software based encoding or modulation, can I add any hardware accelerator to speed up the process and reduce the network latency?
If there is any available hardware accelerator for the said objective, available in the market ready to use and buy?

That is something you really should email Digi support about and include your configuration of the radios.
