Dear Quectel Support Team,

I am currently using the Quectel EC200U-CN module with the following firmware:

Current Firmware: EC200UCNAAR02A01M08

As part of our development, we require full STK (SIM Toolkit) support to interface with our custom SIM applet. However, in the current firmware, the AT+QSTK and related commands do not function as expected.

I would like to request:

  • The latest firmware version for EC200U-CN with STK support enabled
  • Any associated tools (e.g., QFlash) and upgrade instructions
  • Confirmation of STK feature support in the provided firmware (especially AT+QSTK command compatibility)

This firmware is crucial for our STK testing and integration in our production environment.

Please share the firmware and related files via direct message or to my registered email address.

Thank you in advance for your support.

Best regards,
Sabuj De
