Hello,
I'm working with B-WL5M-SUBG1 hardware for experiencing STM32WL5MOCH6U.
I ran the application from Repository\STM32Cube_FW_WL_V1.3.1\Projects\B-WL5M-SUBG1\Applications\Sigfox
I got current of about 2.3mA in standby mode instead of less than 1uA as specified in the datasheet and I discovered that the 5V_PWR LED(LD4 Green) was ON.
I broke the SB14 to prevent the 5V_PWR LED from turning on:
Current down to 900uA-950uA band with this move.
After that I applied this post's recommendations.
Current down to 875uA-810uA band.
But I unfortinatelly I'm still far away from 1uA. Anyone has soluion?
