I have a EC200U-CN module purchased form robu

On trying to send AT_CMGF=1 command to the module gettting error
[2025-04-28_00:06:30:278]AT+CMGF=1
[2025-04-28_00:06:30:278]+CME ERROR: 58

here are my module details (for ATI command)

[2025-04-28_00:07:49:275]ATI

[2025-04-28_00:07:49:275]Quectel
[2025-04-28_00:07:49:275]EC200U
[2025-04-28_00:07:49:275]Revision: EC200UCNAAR03A01M08_BT_OCPU_QPY_BETA1207
[2025-04-28_00:07:49:275]

hi smt

May I ask if you plan to use the Quecpython solution?

In Quecpython, most of the AT commands have been removed. So it is recommended that you use the API.

please refer to this link

Hi Felix.feng-Q,
Thanks for your response.

As we already have a different microcontroller using the EC200U-CN module for GSM functionality which is programmed in C, we will need to add human resource for python with the module, which will lead to cost and time delay in work implementation. So we are not in position to use Quecpython currently in this project as we are nearing the deadlines.

Kindly guide us in updating the firmware.

Best regards,
