I am currently using the Quectel EC200U-CN-AA module and have successfully upgraded to the latest firmware.

1. LATEST FIRMWARE CONFIRMATION Is EC200UCNAAR03A17M08 the latest stable AT firmware for EC200U-CN-AA? Or is there a newer version available?

2. AT COMMAND MANUAL Please confirm which is the latest AT Command Manual version for firmware EC200UCNAAR03A17M08. I currently have: - quectel_ec200ueg800geg91xueg915g_series _ at_commands_manual_v1-2.pdf. Is this the latest version? If not, please send the latest manual.

3. BAUD RATE CHANGE AT+IPR=9600 returns: +CME ERROR: Operation not allowed . We are connecting via physical UART pins (Pin 67 MAIN_TXD, Pin 68 MAIN_RXD) using a CP2102 USB to serial adapter.

Please confirm:

a) Is AT+IPR supported on EC200U-CN-AA?

b) Is AT+CBAUD the correct command?

c) What is the correct command to change the UART baud rate permanently?
