Deep sleep power consumption #247

Open bmghirbi opened 8 months ago

bmghirbi commented 8 months ago

Hi, I read here: https://github.com/Xinyuan-LilyGO/LilyGO-T-SIM7000G/issues/3#issuecomment-645846015 that power consumption in sleep mode is about 300uA

I am trying to reproduce this with sample code esp_sleep_enable_ext1_wakeup(); esp_deep_sleep_start(); and the 20200415 version of the board. However, I am getting 30mA.

How can I achieve low power consumption as low as 0.3 mA ?

Is there some specific hardware modification required ?

30 mA sounds like the 36 mA at https://github.com/Xinyuan-LilyGO/LilyGO-T-SIM7000G/issues/3#issuecomment-597619991 with the GPS antenna connected.
