I am using a XBee Pro S2C and need to transmit data to about 1.5 km away. I tested the module at a place far from people and other obstacles but range was about 50 or 75 meters. So I thought I should be using boost mode and my questions are:
(I am asking about effects on range in all "does it matter" questions.)
1) How can I enable boost mode?
2) Does it matter which protocol I use? (Digimesh, Zigbee, 802.15.4)
3) Does it matter which serial interface I use? (SPI, UART)
4) Does it matter which serial interface protocol I use? (Transparent, API)
I am sorry if answers are something very easy to find. I am totally new to XBee.
Thanks in advance.
