Has anyone tried to use the RI0 output pin of the ADH8066 to answer an incoming phone call.
I have got most of all the other functions working fine, but RI0 just stays high when being called from another phone.
Maybe I’m missing something?
I’m trying to do the same, but instead use it as a SMS indicator for when a new SMS arrives, otherwise I have to constantly monitor the serial line.
Has anyone figured this one out? Apparently you can use +PSRIC on other GSM modules to set this up.
To turn on the RI0 pin to indicate a ringing condition:
AT+SFUN=RID
To turn off:
AT+SFUN=RIN
