you can monitor the voltage in the EM160GL ?

Thanks for your query in Quectel forums.
You can test the voltage from the test point of our m.2 development board or your terminal to power the module to the test point.
Thanks.

I gave this command which returns a voltage, /interface lte at-chat lte1 input=“AT+CBC” is there a more specific one?

Hi,
I can share the introduction of AT+CBC command with you

Thanks.

the em160 has no batteries, so is it the modem’s supply voltage?

Hi,
What do you use to monitor the voltage of the module? If your EM160 is packaged in M.2, it is not easy to measure the Vbat voltage.

i have a m2 to mpcie adapter i measure with fluke multimeter the pin2 in bottom side. the voltages seem to be similar to the at+cbc command.

Hi,
AT+CBC gets the voltage of module Vbat_BB.
Thanks.

what do you mean by the Vbat_BB module the em160 has no batteries.

Kerr.Yang-Q · August 25, 2021, 2:08am

Hi,
You can use the VBAT_BB voltage queried by AT+CBC as the power supply voltage value of the EM160 module, not the battery, thank you.
