Hello,

I have "old" ESP8266 with AT version 1.3.0, I use AT+CIUPDATE to update the AT version, a first update is made to AT version 1.6.2.
Normaly the curent version is 7.0.1 and if i try again AT+CIUPDATE i have this:
+CIPUPDATE:1
+CIPUPDATE:2
+CIPUPDATE:3
+CIPUPDATE:4

OK

But the version after update is alway 1.6.2 ...?

Is somebody as any idea ?
Thanks

1.6.x is the latest version of 1MB flash map.
1.7.x is the latest version of 2MB flash map.
Since the AT firmware supports more and more functions, 1MB flash is not large enough to store the new AT firmware.
