UART_RI for incoming sms txt

Post by aaronhoward »

Hello,

I am looking for the AT command to get the UART_RI pin setup to pulse low when a text is recieved. If anyone knows please give an example.

Thank you,

Aaron

I took a quick look at the SIM800 datasheets and unfortunately I don't think there's a command to make UART_RI change on SMS delivery. You might take a deeper look to be sure though, here's a handy link to the datasheets (command manual has all the AT commands): https://learn.adafruit.com/adafruit-fon ... /downloads

That doesn't make sense you mention that capability in the tutorial on the website. The schematic even mentions it in the top right corner.

It looks like it's buried a bit in the hardware datasheet, section 4.6 RI Behaviors of the hardware datasheet has the same table as the schematic mentions:
State - RI response
Standby - High
Voice call - The pin is changed to low. When any of the following events occur, the pin will be changed
to high:
(1)Establish the call
(2)Hang up the call
Data call - The pin is changed to low. When any of the following events occur, the pin will be changed
to high:
(1)Establish the call
(2)Hang up the call
SMS - The pin is changed to low, and kept low for 120ms when a SMS is received. Then it is
changed to high.
URC - The pin is changed to low, and kept low for 120ms when some URCs are reported. Then it is
changed to high. For more details, please refer to document [10].
I don't see any AT commands mentioned to enable this so I assume its the default behavior. Try skimming through the command datasheet to see if there's anything for the RI behavior--I searched it for 'ring', 'uart_ri', etc. and didn't find anything.

It sounds like it may work that way by default I hope...
