GPRS Signal - Serial Communication #5

Closed crised closed 11 years ago

crised commented 11 years ago

At the unit, there are 2 leds.Green And Red.

It's crucial to know when there is acceptable GPRS signal, so we can have the red light on, and turned off when there is enough GPRS signal.

We can leave green led off, and make it blink when communicating with the server.

For Modbus Tx/Rx, electrical device has leds for that.
