We have many BG96 modules with BG96MAR02A08M1G_01.012.01.012 firmware and we need update it by DFOTA and we will need the Delta firmware for upgrade it. Another Delta firmware for downgrade will be apreciate too.
Can you send us the delta upgrade firmware or tell our how can we download it, please?
We don’t know which is the upgrade delta firmware versión for improve our current version
Thanks for the reply, but I’m trying compress the .BIN file for the DFOTA procedure and the file .ZIP have any problem. I can see 506 error, if I put this update.zip in “fota” local folder and send the AT command AT+QFOTADL=1. (Quectel_BG96_DFOTA_User_Guide_V1.1 p.14 point 4.2).
Can you send me the compressed .BIN files in .ZIP format, please. Have you any Application Note about it? I don’t know what I do badly in the compression procedure.
Yes, I only modify the .bin to .zip. Now the BG96 module download from HTTP server the delta file, save it in “fota/update.zip” and install it with AT+QFOTADL=1 command, perfectly.
Now, my problem is with the command AT+QFOTADL=“<URL_HTTP_Server>/update.zip”.
I use the BG96_DFOTA_User_Guide_V1.1 p.13 point 4.1. For suppot me but , allways show me:
All the comands in the example was OK, but finally, It show the error. Can you tell me the command AT+QFOTADL=“<URL_HTTP_Server>/update.zip” behaviour for undestand the fail?
The error 701 is “HTTP(S) unknown error” and it is really confuse. Because the HTTP comunication is OK by the other way that I explain you at the begining of this text.
The fota_apn is correctly config.
May be we need config the HTTP acces too or the command:
AT+QFOTADL=“<URL_HTTP_Server>/update.zip” do all of it?
I only set the FOTA procedure, like example in your BG96_DFOTA_User_Guide_V1.1 p.13 point 4.1
Is this enougth?
