7.3 Quick use guide for IO reading, IO output and PWM output

For the functions of IO reading, IO output and PWM output of E104-BT05, a guide is given here. In some cases, MCU

is required to collect and control some signals. The E104-BT05 module can be used to replace MCU in collecting signals

and controlling equipment.

1、Read the IO1 input signal value, use AT instruction "AT+IO1?" to read the signal of IO port. (This pin can be set as

signal acquisition device according to the demand, and then the signal can be acquired through other devices or mobile

phone APP)

2、Set the IO2 output. Set the output level by using AT instruction "AT+IO2=xx". (This pin can be set as control pin according to

the requirement, and the target device can be controlled by other devices or mobile APP)
