HW_TRIG pull down time, enter CMD mode

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?

Dear ExtSol

It takes some time to enter CMD mode.

WIZ107SR enters CMD mode after network configuration after booting.

The time is estimated to be up to 2000ms after booting.

Is this a problem for you?

Scott
