I use a GPIO pin to switch between communication interfaces of my modem. When i set output to 1 modem switches to receive mode, and when i set it to 0 modem switches to transmit mode.
The problem is that the switching between receive and transmit mode has some delay. I want to reduce this delay. i want to know if there is a faster way to set GPIO pins. I use the following AT command approach.
adl_atCmdCreate( "AT+WIOM=1,\"GPIO22\", 1,0\r", ADL_AT_PORT_TYPE(ADL_AT_UART1, FALSE), NULL, NULL, NULL);
i use Airprime Q2687RD, FW R7.45
