Hi, thank you for this very useful repository. I successfully installed the firmware and used the web application integrating it with bt functionalities (I didn't modify the original code, but only added a library written by me). Now i am encountering some problems:

1. after reuploading the code sometimes my serial monitor is empty, and every time i upload i need to select again the port beacuse the device disconnects. When the serial monitor is empty the device can anyway comunicate with BT-
2. My Wifi network failed the ping test and i can't connect to the AP in order to modify my setting and try a new Wi-Fi connection. I tried to delete /data folder from my SD but it seems that my Wifi keeps saved in some sort of cache (sorry i'm not so expert).
3. Is there a way to start the device every time in AP mode without Wifi connection? my AP doesn't appear in my wifi list as before.
   4)Extra question, is there a way to disable motion detect by default?

I also tried to clone the repository(coping the /data folder of the repo on microSD) and run the 'clean' code but the mentioned problems persists. Tried also to put to false the usePing variable but still not works.
Edit: Also this appears:.......[00:14:29.154 WARN startWifi] SSID ISTC_Floor_4 not connected WL_IDLE_STATUS

i've not used bt, but I dont think it can coexist with wifi as there is only one radio

[giampierobartolomei]

Hi, as I said the problem persist when I run the Original code from your repository (so without bluetooth)

[s60sc]

your wifi signal strength is low, try moving esp closer to router.
To stop ping: Edit Config / Wifi / Use ping then press Save and Reboot

Ok thanks, last question.
Even if the LOG INF prints confirm the AP connection, i can't find it in Wi-Fi list on my devices, so i can't modify my preferences from the webapp. Then, I don't know how, even if i delete files in /data folder in my SD, my Wi-Fi "ISTC_Floor_4" SSID & pass keeps saved, so i can't restart the AP like in first installation. So, i want to ask to you how to set the CAM to work in AP mode by putting the correct settings by modifing the code, in way to have a stable AP connection with my XIAO ESP 32S3. For my application it would also perfect to work only in AP mode.

[s60sc]

In Access Settings / SSID delete entry then Save Settings then Reboot
ESP AP only has limited range, devices need to be close by

[giampierobartolomei]

For my application it is good to stay close to the camera, i was asking if there was a way to modify these settings from code since i can't open the application
