The serial port overflows [updated for clarity] when the module is switched on. This works fine on a standard esp8266 but it seems to have overload issues with the wroom-02. I am flashing with a 2mb file size including a small file system.

what do you mean overloads?

[ehammock]

Hi, many thanks for coming back to me. When I look at the serial monitor it continually scrolls with hex data. It doesn't do that with and Esp01 only the wroom-02.

[tablatronix]

what example are you using ?

[ehammock]

Hi, the builtin BASIC example in arduino under library wifimanager.

Ill check but thats odd sounds like its crashing or a boot loop?

[ehammock]

Yes, it seems to be on boot.

I'll take another look this evening. My gut feel is that it is related to the flash size which on the wroom-02 I think is smaller than the standard esp8266. I would like to get it working though, as WiFi manager perfectly suits my need, also the wroom-02 'WiFi battery' is a perfect physical solution for my need.

Thanks.

What is a wroom 02?

[tablatronix]

oh yeah these are pretty old, I think i have one

[ehammock]

Many thanks.

I'm happy to contribute to your project (buy a coffee, patrion, fiverr etc) if we can get this working.

Thanks, Edward.

Can you maybe add a delay on boot so you can see if there is a crashdump or something

If I use a D1 Mini (ESP8266 inside) everything works fine. I hope this helps a little..
