Question about OTA

[nibbler79]

Hi,

first, thank you for the great work - I am using your design since 6 Months, without any big issues (controlling 4 MHI SRK via mqtt from fhem)

I just recently noticed that all 4 modules open an hotspot allthough configured and connected.
Is this used for OTA? Or is OTA done via the usual connected WLAN and it is a bug that the hotspot mode comes up in normal "production" mode?

Thank you for your input, and best regards
Markus

Hi Markus,

Great to hear that you got it up and running. I also noticed the open hotspot at some point. However, I relocated to another city a while ago and left the aircons including the arduinos in my old house. So I no longer have access to a working unit for testing what is causing this.

It looks like this is caused by the ESP running in dual mode as described here:
tzapu/WiFiManager#229

Can be solved in the code, but maybe easier to replace the Wifimanager library with this one:
https://github.com/kentaylor/WiFiManager#selectively-operates-in-dual-mode

I hope this version of wifimanager is directly interchangeable with the current ESP2MQTT code.

Let me know if this helps.

Regards,
Rob
