Hi,
I have a NB IoT 2 Click and I have seen that the power consumption is around 6mA in PSM mode (should be around 3.5 μA). I am powering the board through pins 3v3. Any idea what it could be?
Thanks

Re: NB IoT 2 Click high power consumption
Hi,
Can you tell me how the BC66-NA was set to sleep mode?
The 6mA is strange, since none of the available modes use 6mA.

Ivan.

Re: NB IoT 2 Click high power consumption
Yes, it goes into PSM mode but I have seen that vdd_ext is high, and it should be at 0V.
Whatever I do, the minimum consumption I get is 6mA.

Re: NB IoT 2 Click high power consumption
Hi,
If the voltage on VDD_EXT is high, then that means that the module did not enter sleep mode.
Did you use the AT commands below?
AT+QSCLK=1

Re: NB IoT 2 Click high power consumption
Yes, I executed that command, and the module gives me a message that it is entering PSM mode but I don't know why it doesn't do it.
Re: NB IoT 2 Click high power consumption
nothing?
I would like to know if it is a hardware problem and how to solve it.
