I mistake that set Class C for testing current consumption and a problem is solved by changed Class C to Class A. I measured a current 9.8 uA during sleep mode.
I have a new issue about cubecell connect to GPS module ATGM336H
I connect GPS module to cubecell using Vext —>3.3V, GND —>GND, GPIO —> TX,PPS
—> active Vext supply voltage 3.3V by digitalWrite(Vext, LOW);
—> sleep Vext cut voltage by digitalWrite(Vext, HIGH);
when sleep I measure current 0.98mA and
voltage between Vext and GND equal 1.1V (I think voltage from Vbat of GPS module)
How to reduce current during sleep mode
