On the site, it mentions that the bc66 dev with usb can achieve 126ua. However, I am only getting over 200ua in pure PDM mode using AT+QPOWD=0
Is this an error on the description?
Did you enable power saving mode?
Check if it is enabled with:
AT+CPSMS?
If it is disabled make sure to enable it with something like:
AT+CPSMS=1,,,"01101010","00000101"
