Hi Dear Qualcomm Support Team
I tried to flash my EC200U-EU AP-N05-SGNSA module with firmware
QPY_OCPU_V0005_EC200U_EUAA_FW
but after programming the module it does not turn on and its COM ports do not appear (I have a module on a miniPCI card connected to Windows via a USB adapter).
It enter the module into bootloader mode by shorting the USB BOOT pin to VDD EXT
Can you upload a working fw to this module with python support?
please send me last FW without Python too
I don’t know what FW version was on module!!! 
i have another module
Quectel
EC200U
Revision: EC200UEUAAR03A16M08
but i don`t know what FW version was on brick module!
hi zebel
I have confirmed with our internal team that EC200UEUAP and EC200UEUAA share the same EC200UEUAA firmware.
May I ask if the firmware flashing process showed a success status when you flashed the EC200UEUAP module?
yes i saw PASS status
Hi Felix,
I’m really confused, I’m struggling with a persistent CME ERROR : 58 on every GPS-related command, for this reason I was trying to update the firmware with the QPYcom tool but neither AA et AB version worked. The confusing part is that the module I have is the EC200UEUAP but the FW flashed on it is the EC200UEUABR03A21M08_OCPU_QPY , so an AB version, which I guess could explain why GNSS isn’t working.
Can you tell me what steps I should take to get out of this situation ?
Thank you in advance.
hi Thomas
1, In QuecPython, most AT commands are not supported. To use GPS, please use the dedicated API interfaces for debugging. Refer to the link below.
quecgnss - Internal GNSS Resolver - QuecPython
2,If your module is EC200UEUAP, please use the EC200UEUAA firmware. The firmware can be downloaded from the official website.
