when we configure the GPIO21 using AT+WIOCFG to be high we find that the GPIO does not go high until late in the boot-up sequence. How can we get the GPIO to go high earlier in the boot e.g. In our case, we have simcard switch controlled by GPIO. we would like to control this gpio before the WP7608 has searched for the simcard
It seems to us that the WP7608 is pulling down the GPIO during the early boot up. Is this expected?
If so how can we change this behavior
