I have converted a product from GR64 to Q64 but I have a problem with the Ring Indicator. I need the Ring Indicator line to toggle whenever an SMS is received. I have configured the modem with the following: AT+CNMI=2,1,0,0,0 AT+WRIM=1,6,33 This should toggle the Ring Indicator whenever an SMS is received. This does not appear to happen. I have configure the UART to generate an interrupt whenever the modem status changes, ie ring indicator, but the interrupt is never generated. I have scoped the Ring Indicator line and I do not see any pulses on the line. If I revert back to a GR64 with its firmware, everything works perfectly. Any ideas? Am I missing something? ---
