How to get 2.1uA with LoRa-E5 in low power mode?

yesterday I used stdio chip , and power from USB port, when it I working it wa 15mA at deep dropped to 5mA, today I texted powering the module directly without ftdi, now at deep sleep mode 0.5mA draws, still this is too high.

also now I cannot get out of deep sleep mode seems they AT command dent work , AUTOOFF hex format FFFFFFFF61742B6C6F77706F7765723D6175746F6F66660D0A. is this in command lit written should get out of the deep sleep mode but doesn’t ,do you have any experience?
