I am working on implementing AGNSS on a project with an L86 receiver. Our L86 chips are running FW version L86NR02A02S.
Following GNSS_Flash_EPO_Application_Note_V1.0, I first tried writing QEPO data via the binary interface but failed to receive any acknowledgement packets from the receiver.
I then found an updated application note, Quectel_Lx0Lx6LC86LLG77L_AGNSS_Application_Note_V1.2, that suggested writing the QEPO data via NMEA commands. I tried this approach as well, but again the receiver does not respond with any acknowledgment packet.
Is AGNSS functionality supported with this FW version? If not, what is the latest documentation for performing FOTA to a newer L86 firmware?
