I am updating by FTP
I’m looking for a .bin file
Which one is in the folder?

I am using this method

hi,
.bin file is a differential file, so I cannot provide it. If you need it, please describe relevant requirements in detail and send an email to support@quectel.com.

I want to update the module because the SMS section of the module does not work properly

I did this first with USB but did not get the right results
And I was going to do it by OTA
According to the module document itself
