Thanks for your reply
The core firmware is 640b09gg.Q2426B 1272884 070403 16:03 and i want to upgrade with 641c09gg.Q2426B 1349424 092404 15:49. it’s ok, but its strange that… when i want to send the file not appears the the DCD signal in my hardware and the download not start.
I meant with
+WDWL: 0 not appears the next string :… (characters) and not start the download like others modules and the DCD signal in my hardware not appers it’s like to the module not response.
It’s strange too that i can’t set the next instruction
an error returns.
I have trying too send others commands like to AT#DISPLAYIP (error returned #CME ERROR: 35867), AT#VPPP, etc… (i think i actived this commands with the AT+WOPEN=1). In some
modules the commands are accepted, but the modules with the core file 640b09gg.Q2426B 1272884 070403 16:03 not works.
They are 12 or 11 modules with this bug. All of that is in the same modules.
