EHS8 Power down | Thales IoT Developer Community

Hi,
I'm programming an EHS8 with the Java API. The program basically starts, makes some sensor measurements, gets the RTC time (AT^CCLK?), sets the ALARM x minutes later (AT+CALA) to restart the module and finally, it is switched off.
The problem is that the module is consuming too much power when it's off. If it's switched off calling the destroyApp method, the module is consuming like 50mA, and if it's switched off with AT^SMSO, it's still consuming 18mA. I'm calling several threads during the functionality, but I wait for them to finish (join method).
Any ideas about which can be the reasons for such consumption?

Hi,
Please check AT^SPOW? for the serial line sleep ****. If the response is 1,0,0 you have full power consumption for the serial line. The response 2,1000,3 is the default power save ****.
Another thing is USB: While a USB connection is active, the module will never switch into SLEEP ****.
See the EHS8 AT Manual, 2.1.3.1 Reducing Power Consumption.

Hi,
Thanks. The consumption problem was not from EHS8, it was from an unappropiate pullup resistor in the AUTO_ON signal. Anyway, thanks for the reply.
