Hello,
I am trying to run the QFOTADL to update the firmware of BC660K-GL.
Basically, I did the following steps:
1 - Build the firmware A (let’s call it firmware_old);
2 - Do some very small change, and then build firmware B (lets call it firmware_new);
3 - Go to https://dfota.quectel.com:8443/
4 - Upload firmware_old and firmware_new
5 - download the delta, which was named by the webite as firmware_old-TO_firmware_new.zip
6 - then I uploaded this zip file into my HTTP Server
7 - Then I ran the command AT+QFOTADL="http://xxx.xxx.xxx:80/firmware_old-TO_firmware_new.zip"
Here are the logs:
AT+QFOTADL="http://xxx.xxx.xxx:80/firmware_old-TO_firmware_new.zip"
OK
+QIND: "FOTA","HTTPSTART"
# [->> then it took about 2 minutes to show the below URC <<-]
+QIND: "FOTA","HTTPEND",12
There was no indication in between about the download progress, as the PDF “DFOTA Application Note”.
I would expect some indication like this about the download: +QIND: "FOTA","DOWNLOADING",x
, where x
is the percentile progress.
Also, I do not know why it returned the error “12”.
Did I do some wrong step?
Here is my module’s firmware version:
ati
Quectel_Ltd
Quectel_BC660K-GL
Revision: BC660KGLAAR01A04
OK
UPDATE 1:
Yes, the error code 12
means: "Download failed"
.
But still, it took so long, and I do not know why it fails.
The HTTP Server is publicly available, and I can download the zip file normally.
UPDATE 2:
I used Wireshark to sniff in/out packets, and my firmware keeps sending a “hello” message over UDP (in a specific port), so I can see in Wireshark that I am receiving the “hello” messages.
However, when I ran the AT+QFOTADL="http://xxx.xxx.xxx:80/firmware_old-TO_firmware_new.zip"
I do not see any different traffic, only the “hello” message on UDP.
