Note again to follow national regulation. In EU +27 dBm at 433 MHz is not allowed. +27 dBm at 868 MHz will typ give 5 km free line of sight if configured for ultra-narrow band low data rate setting.

RC232 Q&A Related Knowledge Base Posts - [RC232] We are in the process of evaluating the RC1240, The only thing I’m not sure about at the moment is how to implement a busy check before transmitting [RC232] “We are drawing a new board which used your module RC1180. We are in a final phase. For the interface with the our µC, we connected only the pins : – RxD & TxD for module configuration and normal use for communication – Pin Reset, Pin 19, Pin 20 : for future programming (case of firmware update) Also, we connected the pin Vcc and ground with recommandations described in your data sheet. I would like to know, if we can use functions of test carrier transmit, modulation transmit and permanent receipt with only the pins RxD and TxD (RTS, CTS and config not connected to our µC but available on test pads). Do you have a procedure to put this module in test mode. For a firmware upgrade, could you confirm us that we need only Pin 19, 20 and reset ? “ [RC232] Is full-duplex scheme feasible with the modules?
