Hello, I’m using TD210: IoT Cellular Modem version Quectel UC200T.
I want to ask about a problem I’m having and see if I can get help from you please.
The problem I have is the following:
When I use the AT+CMGR=0 command to read an SMS message in PDU mode, I get the following response.
+CMGR: 1,.24
0891254901001014F0040c912555521387260000428091711382 4a 054769b1e804
OK
By decoding the string, I have the answer I expect, I want to emphasize that the timezone I get from the string is
(-24), I am in Mexico City.
The problem is found when using the command AT+CMGR=0 in text mode, the response I get is the following.
+CMGR: “REC READ”, “+525536357992”, “08/24/19,17:31:28+104”
GREEN
OK
As you can see in the response, the time zone does not match the one I get in PDU mode to read a message.
I consulted my problem in the forum and they told me that the problem is due to a problem with the firmware and the way the module encodes the response in text mode.
If the problem is due to the firmware, how could I update it? If the problem is due to another situation, I would like to know how I could solve it.
The module and review that my IoT Cellular Modem comes with is as follows.

Thanks for the attention.
