The modem enumerates only with one malformed USB interface (vendor class, no AT port) so I cannot issue AT commands. I have the firmware package you sent.
What is the exact EDL entry procedure for RM530N-GL (bcdDevice 0x0504)?
I have the M.2 card exposed on a Waveshare USB adapter. Please specify:
- Which PCB test points to short (with a photo if possible), OR
- The M.2 connector pin number to pull to 1.8V, OR
- A USB vendor command / QDownload tool that forces EDL
Also please confirm whether USB_BOOT is shorted to GND or pulled up to 1.8V on this board.
