Information for the LG290P is showing up on the English language site. No HW guide or protocol reference, but there is a firmware upgrade guide named Quectel_LG290P(03)_Firmware_Upgrade_Guide_V1.0.pdf and it refers to LG290P03AANR01A03S, while my module shipped with this version:
$PQTMVERNO,LG290P03AANR01A02S,2024/02/05,18:22:23*11
Could I get a copy of the new firmware please?
