Shield LEDs turn off when serial connects - 'normal power off' response
Tonny12138 2024-07-11 16:18:31 49 Views0 Replies I have tried restarting the shield multiple times, each time the shield initiate normally with Stat and Net LED turned on. The moment I connect to the shield via serial, both green light would turn off. I had tried diagnosing the problem with Module Tester(Serial monitor). On the rare occasion a connection was establish, it would display a response like normal power off. What's the problem with it?

Once the module detect the serial signal_Reset, it will reset, then the module would power down, namely the State and NET LED would turn off. And the the Reset signal can be triggered by any one of these operation
① hit the botton_RST(reset) on the shield/ Arduino card
② when you pull the switch_S1 from Prog to Comm (or contrary)
③ when you open Arduino Serial Monitor or connect the serial port by other Serial Testers.To reboot the module (light up the State&Net LED), you can hit the button_Reset or you can re-open the Serial Monitor.
