    Welcome.

    I bought an ESP-07 module on Allegro, it is something like this:

    ESP-07 (ESP8266) module - some strange symptoms and a software update

    except that mine is similar, but I can see that it is not like the original, because the antenna is all white and there is no inscription "Rainsun" and the tracks on the other side of the board also do not coincide with those that can be found on the Internet. But the module works and I am already playing with it.

    I noticed only one small problem, the command "AT+CIOBAUD?" does not work, because it returns ERROR every time. The module has been running at 115,200 since new, so I issued the command "AT+CIOBAUD=9600" and it now connects at that speed. There is another rather surprising thing well when I connect power to the module it sends me this information on startup:

    ESP-07 (ESP8266) module - some strange symptoms and a software update

    after it spits this out, when I want to send it something, for example an "AT" command, then instead of answering me "OK" it remains silent for a while, then it gives me bushes and ERROR and only after some time it starts to answer normally. This can be seen here:

    It looks like it needs time to tune the UART? It's a bit strange.

    With these two errors in mind - the "AT+CIOBAUD?" command not working, and these temporary UART problems, I decided that I would update the soft because maybe that would help something.

    At first, I wanted to check what version I currently have. So I typed in the command "AT+GMR" and got this response:

    AT version:0.40.0.0(Aug  8 2015 14:45:58)
    SDK version:1.3.0
    Ai-Thinker Technology Co.,Ltd.
    Build:1.3.0.2 Sep 11 2015 11:48:04
    OK


    From what I have seen so far on the internet I should get something like this after this command:

    0020000903


    So maybe colleagues know how I should read the software version from this information I received? Because from what I think it is 0.40.0.0? So what is newer or older?

    And now I don't know whether to do the update or not because I don't want to lock it somehow?

    Thank you for clearing up my doubts about the communication. I was already a little worried that it might be some kind of defect.

    As far as the software update is concerned, just from what I've been able to find on the internet it's enough to execute the command "AT+CIUPDATE" and the update will update itself.
    However, I'm wondering if it's not better (if possible) to make a backup copy of the current software?

    This is not necessary.
