Hi All, I have a question.
If Wismo 218 receive a message (SMS) it stores tme message into the SIM memory.
The only way to keep under control the status of received messages is to poll cntinuously the +CMGL command and parse the result.
Is there a way to have an hardware signal from the wismo218 showing a new SMS is incoming?
We can actually use +PSRIC to control the RI (ring indicator) pin behavior on WS218, e.g. high RI pin on SMS reception (RImask 2).
Please read section 8.6.12 on AT command guide of WS218.
