We have an EC200T module, firmware as reported:
AT+CGMR
< EC200TEUHAR05A01M16
After lots of experimenting with settings, we cannot set up a data connection any longer.
So to eliminate our changes as a source, we’d like to reset the module to its factory default. We cannot find a command to do so. The AT&F0 command only resets some settings but not all.
Could you please assist us and provide a way to completely reset the module?
Hi
You can try to restart the module or re-burn the firmware. I will send you the latest firmware via email, please check
Haven’t received any e-mail yet. Whom should it be from?
Hi Milo
I’m very sorry about this. I have sent you the firmware before, but it may be due to some reason that you did not receive it. Have you received it now?
Still haven’t received it.
Our supplier was kind enough to assist us with that.
After replacing the firmware, the module worked properly again.
It would be nice if we could just download the firmware from your website instead of spending weeks to locate it.
Hi
Thanks for your feedback. Please forgive the previous emails that were not sent correctly due to some reasons.
Best wishes
Hi, I’m on a similar situation with a EC200AAUHAR01A06M16, I tried to enable the UAC feature with AT+QAUDCFG=“uacmode”,1 and then power down / power up thge module and Windows 10 restart every time the USB cable is connected.
Can you help me with re-burn the firmware?

Hello, could you send me the firmware for EC200TEUHAR02A10M16. With a SIM card, the module constantly reboots. Thank you
Hi, I am using the EC200U-CN module,
AT+CGMR
EC200UCNAAR02A10M08
OK
Whenever, I try to play the AT+QTTS:2,“Hello” immediate response as +QTTS:0 is occuring. I have tried to debug it. But couldn’t get the audio output. Can you help me with this.
Below is the AT commands flow to get Text to Speech output:
AT+QAUDSW=1
OK
AT+QAUDPASW=1
OK
AT+QAUDMOD=2
OK
AT+QTTS=2,“hELLO”
+QTTS:0
Here, the audio output is Speaker, for the first few times, I got the audio output as character by character(It is not reading in string format). So, after that I am not getting the audio output and the +QTTS:0 is given as response after 200ms.
I want to reset all the settings of my EC200U-CN module, but couldn’t find the AT commands for it. Please share me the AT commands or any other way to reset whole settings of my module to factory settings.
And I have another module, in which I was not able to send or receive any data through AT commands. Is there any other way I can debug my module.
It would be helpful for me if you share the related documents or commands or debugging steps as soon as possible.
Thank you.
