The RC232 protocol has two modes.
Configuration or traffic. In traffic mode the radio is transparent. So the bytes sent into one module (UART) comes out on the UART at the opposite module.

- [RC232] “I have problem to wake up RS1240 from sleep mode, in fact I can’t wake it up at all. According to documentation, config pin should be asserted when going to sleep mode, and then positive edge should wake ip module This is code I use: Config Portd.3 = Output : Modem_config Alias Portd.3 Modem_config = 1 ‘ ———— PUT MODEM IN SLEEP MODE Modem_config = 0 ‘ Assert Config pin Waitms 5 ‘ MAX Time from CONFIG pin is set low until prompt (“”>””) Print “”Z””; ‘ Goto SLEEP mode . . . Sub Send_packet Modem_config = 1 ‘ Wake up form SLEEP mode Waitms 60 ‘ Wait 60 ms to get out from sleep mode Print “”X””; ‘ Goto idle mode Led_tx = 1 Printbin Paket_start Printbin Data_packet Led_tx = 0 Modem_config = 0 ‘ Assert Config PIN Waitms 5 ‘ MAX Time from CONFIG pin is set low until prompt (“”>””) Print “”Z””; ‘ SLEEP mode End Sub But, module stuck in sleep mode, and dont send enything. When I comment all lines regarding sleep mode, module work fine. Where I’m wrong? I should deliver device this week, and this is only problem I have to resolve. “
- [RC232] Do you use a CCA/MA that’s in error or drifts like RSSI? What is your proposed solution for this issue?
- [RC232] We are trying to configure our modems RC2500HP 201545H to use them at a data rate of 250kbit/s, following the datasheet rev 1.22. However the communication fails at this RF rate. Back to 100 kbit/s the communication is works again.
