XBee Retry in API mode
hello evryone,
i using xbee arduino uno boards communicate between 2 such nodes. (xbee 24)
i stuck in 2 basic aspects regarding networking in xbee in api mode:-
1. have set baudrate on both nodes @ 111111 bauds (16 mhz/(16*111111.11)= 9, integer value). using api mode read data , send receiving node. though using same baud rates @ transmitter , receiver find there loss of data @ receiver. api mode reports error indicating dropping of data packets. want know how enable retries? default enabled? read takes 200ms resend ack receiver tot transmitter. understand basic ask need clarification on aspect. plz help.
2. if want increase data transfer rate, other devices can choose acheive without causing loss of data.

which model xbees?
how data being sent? how often? xbees low-bandwidth devices , have small buffers.
the xbee mac layer retries default. if transmission fails, retries @ application layer may not depending on cause.
why unusual baud rate? use 115200 or 57600. there no requirement 2 xbees use same baud rate. whether or not should have no effect on reliability of transmission.
in experience xbee zb (f.k.a. series 2) modules, successful transmissions return ack in < 50 ms. did 200 ms number come (link?)
