2.3.RESET
Figure 5 Reset Header, Switch
2.3.1. Reset Switch (SW2), Reset Header (J4.9)
⚫The voltage level of RESET is 1.8V.
⚫There is a 1.8V pull up circuitry inside the module.
⚫When a host board is controlled by the reset switch, the default attribute is set as INPUT. For
resetting the device, the LOW value should be maintained for 1ms and then configure it as
INPUT.
Example Code
pinMode(8 ,INPUT);
pinMode(8 ,OUTPUT);
digitalWrite(8, LOW);
delay(1);
pinMode(8 ,INPUT);
2.3.2. Software Reset (AT Command)
The device can be reset by using the AT+Command ‘AT+RESET’. Please refer to the AT+Command
manual for more details.
