TESEO LIV4F low power
Hello,
I am currently using the EVB-LIV4F and using page 8 of the UM3212 document to measure the current draw of the module. I am then placing it into SW-standby mode by sending the $PSTMFORCESTANDBY,<seconds>,1 command that I found on this post: https://community.st.com/t5/gnss-positioning/teseo-liv4f-wakeup-interrupt-and-nreset-confusion/td-p/615973
Under these conditions, I am measuring 0.0mV on the VCC (pin #9) and PM_VCC (pin #10) pins and 9.1mV on the VBAT (pin #7) and PM_VBAT (pin #8) pins. From the conversion given, the GNSS module is drawing 91uA on VBAT and not the advertised 10uA.
Does the evaluation board need to be in a specific configuration to achieve the 10uA? Any jumpers that need to be added/removed?
Where is the documentation on the placement of jumpers? The eval board silkscreen does not have all jumpers labelled (Jxxx) and neither does UM3212 section 6.2...
