STM32WL5MOC power consumption

[alexemdesgagne]

Hello,

I'm looking to measure the power consumption of the STM32WL5MOC component on a B-WL5M-SUBG1 development board.
I'm looking for the power consumption announced by the Sleep Mode datacheet (140nA - 810nA).
I connected directly to JP2 to use only STM and I supply 3.6V and I measure the consumption with Otii software and an Otii Arc Pro.
I measured a cosomation of 112uA, far from what I should have.

Do you have a method for measuring sleep mode power consumption?

Thanks for your help.

Hi

We finally figured out our problem.

Thanks!

Hello,

We have a similar issue: The minimum current consumption is higher than expected: 89 uA (expected: 1-2 uA) after joining (OTAA) successfully.

Do you have an idea what could be the issue?

Board: B-WL5M-SUBG1

Firmware: STM32CubeWL/Projects/B-WL5M-SUBG1/Applications/LoRaWAN/LoRaWAN_AT_Slave

Version: STM32CubeWL V1.3.0 (latest from https://github.com/STMicroelectronics/STM32CubeWL)

Power supply: 5 V via CN4 (E5V)

Current measurement: IDD jumper (JP2) using Joulescope

Thanks!
