I have 2 working devices that use SI4432 @ 2KBPS with GFSK to send a couple of bytes every minute. In an effort to increase range I want to reduce data rate further, doing so gives better receiver sensitivity and hence better range.
I am using RF22 (on arduino) that provides the lowest data rate of 2KBPS. However the lowest data rate is 0.123 KBPS. How do I reduce dta rate to 0.123 KBPS with RF22?
Also the datasheet mentions receiver sensitivity as -121dBm, how much of sensitivity can be expected at 0.123KBPS?
Thanks and Regards, WonderfulIOT
