Hi,
I bought WIZ107SR module.
Process no1:
- After power on, i started both nRESET and HW_TRIG pin low state
- wait 100ms
- set nRESET pin to high
- wait 1000ms
and the serial commands not working.
Process no2:
- After power on, i started both nRESET and HW_TRIG pin low state
- wait 100ms
- set nRESET pin to high
- wait 3000ms
and the serial commands now working fine.
How long time to keep HW_TRIG pin low state before the module entering CMD mode?
