We have just tried the Power state.sleep on a G120H loaded with 126.96.36.199, the real time clock awake nicely the card when the time slice is elapsed.
In full power we seek 120 mA from the 3.3V power supply, during DeeepSleep 18 mA, that current drain seems a bit high especially if we compare with VBAT and the few µA drain of the RTC.
As 18mA is a high current drain to be able to run continuously from a battery, have you an idea to get a lower drain during our long sleep period ?
The module must be awaked twice a day for 2 minutes to sequence I/O ports. The system should run from a battery pack for a month.
using a 1200 mAH battery pack is the target, 1 mA Sleep drain will be perfect
