Hello all!
GPIO2 pin on Q2406B
is known to be multiplexed with RI1 and thus cannot be controlled within OpenAT application. However, the M2106B module, which is based on Q2406B, contains two separate GPIO2 (pin #7) and RI1 (pin #9) pins, which in fact aren’t tied together as one could assume! So, what the GPIO2 pin on M2106B is actually intended for? And how could one conduct its state within embedded application?
