WiFi Server 2.1b6 + EPS07 forgets ssid on restart

Alex_ZHANG

Hi.
I have 2 Duet2WiFi, both running RRF 3.5.0 RC3.
Today I switched one of the board's wifi chip to esp07 with external antenna for better reception.

Interestingly, it starts to forget remembered networks on restart.
connecting via usb, sent m552 s0, m587 and m552 s1, it connects, but once i power off and on again, everything is lost.
I downgraded wifi server to 1.27, everything works fine.
Upgraded to 2.1, Alzheimer again.

I have extra esp12s esp12f and esp07 lying around, cross checked them with the two Duet2WiFi boards I have to eliminate soldering issue.
this only happens in esp07+wifi server2.1b6.

@Alex_ZHANG the DuetWifiServer 2.1beta store the details at a different memory address, which is why you have to re-enter them the first time you upgrade. I know the ESP12S has 2 or 4MB of memory, maybe the ESP07 has less, and less flash memory?

@droftarts yes, that might be the issue. ESP12 has 4MB and ESP07 has only 1MB spi flash. I'll order and try EPS07s with 4MB flash.
But I believe there are duet2 WiFi boards with stock ESP07 out there? Wouldn't that be a problem? I remember seeing someone ordered some from Roland.

And this happens every time I restart the board, not just the first time I upgrade.

@Alex_ZHANG the older Duet WiFi boards that support external antenna use the ESP07S module which has 4Mbytes flash memory. Newer ones use the WROOM-02U instead. AFAIR the minimum supported by the firmware is 2Mbytes.

@dc42 Aha, so that's what the 32s3.bin is for.

I'll use ESP07s. At the same price, what a fool I am to order ESP07 just for the same form factor

Thanks.

@dc42 BTW, if it's convenient for you, could you have a look on my other post about accelerometer? I have a data overflow issue, and input shaper dose (alomost) nothing on long distance move.
