Re: SIM900 Arduino Shield - Sleep Mode

Hey,
I have measured my Arduino (I have switched over to a Pro Mini)
The arduino needs 2-3mAh without removing the Leds in Low Power Mode that waits for an interrupt.
I measured the Shield alone.

GPRS Shield v1

I am trying to get the shield down to 1,5mAh, but the lowest I can get is 25mAh with CSCLK=2 or CSCLK=1 with DTR High

Any ideas?

SIM900 Arduino Shield - Sleep Mode

Hello,

I am currently trying to send the module into low Power mode, but:

AT+CSCLK=2 only drops the module to around 25mAh, after 5s of no data send
and
AT+CSCLK=1 only drops the module to around 25mAh, after pulling DTR up.

This is far away from 1,5mA!
