I couldn’t find any information on what the last option is. I mean the “dyn/thd”.
Can you send me the updated version of “EC200U GNSS Application Note”?
I think dyn/thd indicates third party dynamic support, and there is no reference for any explanation at this time

Hi Herbert
I didn’t know that there exist a firmware with DSDS support. Although I had a document describing the feature for EC200UEU, but I have been told that the module doesn’t support the DSDS and it only support DSSS. Can you send me the DSDS firmware?
thank you in advance

I didn’t receive the email. Would you please send it again?
my email: dezdeepblue[@]yahoo[dot]com
Thanks a lot, I tasted, the new firmware works fine for second SIM fine in DSSS mode (not in DSDS mode). As dezdeepblue said it seems that EC200U-EU doesn’t support DSDS, So I will do my project using dsss function. My previous firmware doesn’t support even DSSS
Hi,
I don’t know if and how anyone could receive the file through this OneDrive/Sharepoint panel. I’ve tried over 7 times with no success to get the file!
Everytime it sent a verfication code to my email (valid for 15 minutes) with a delay of multiple hours, which the code obviously already expired at the time of receive.
I don’t know if anyone has received any file through this portal, but it doesn’t work for me.
Do you have any other way of sharing the file?
Thank you.
I have resent it to you,pls check
