- [RC232] Why is RC1280HP-RC232 shown as ‘Not recommended for new designs’? How much longer will be in production?
- [RC232] “When I connect to the development board using your software (“”RC232 Configuration and Communication Tool””), everything works fine. But when I connect to the development board from inside my own application for the first time each day (e.g. in the morning when the dev. boards have been powered down for a couple of hours), it only sends 0x00s via the air interface, no matter what i want to send, everything is zero. When I then connect to the board once with your software, everything works fine again and also my application afterwards works fine, and I can send everything correctly again. But I have to do this every morning again. Maybe you have any ideas what the reason for this is or what I could do to fix this problem? “
- [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. “
