with the instruction of User guide, there are 3 modes of data rate of XBee-PRO SX, 10kbps, 110kbps and 250kbps. However, the maximum date rate I test with X-CTU is only 40kbps. Ｉhave tried with all configuration of data rate, serial baud rate and also make sure the SNR is big enough (40dB).
so my questions is :
how to get 250kbps date rate with XBee-PRO SX?
what is the relationship with data rate, serial baud rate and the throughput?
