Hi All,
As I'm playing with different GSM modules, I'm stumbling on SIM5320E and SIM5360E that have no easily accessible "RING" pin (like on SIM800/SIM900/etc modules) which I normally use to trap an incoming call/SMS via an External Interrupt of the PIC.
8907 8908
In fact, they do have a "RING" indicator (Pin 69 of both modules) but it is not lead to an external pad or pin which makes it difficult to use unless one solders a wire directly on the chip's pin (I don't even know if it would work - not tried yet).
Since lots of modules seem to be made like that, my guess is that there must be a software method to trap incoming call/SMS.
Shall I start to use UART interrupts (never done before...) or is there another way to go?
