Re: esp32 gatt server sensor data reading

You have to update eddystone packet with new values each time, then set new advertising data and re-start advertising.

I dont know about any, but easy way to get some insight is to compare default partition table for different flash size in arduino:

Re: ESP32 4MB and 8MB Binary Compatibility

You can build and flash 4MB app onto 8MB flash without any changes needed. Just 4MB of flash will be unused. To use 8MB flash you dont have to re-build whole app, but you have to adjust and rebuild partition table and bootloader probably too, as there is flash size option in bootloader (not 100 % su...

Re: ESP32-S2 ROM USB - Custom PID / manufacturer string

I cant answer for sure, but in case of ROM USB probably there is not possible. Maybe with large volumes espressif can burn customized ROM, who knows.
You can also use tinyUSB and in that case check this:

Re: Update 'adv_data_raw' in my BLE ADV application

Why not update adv_raw_data in app_main or any other place you want? Maybe you will need to add some flag in events, that will tell you when you can setup advertising first time, but i believe you can try without it. because Im using the esp_ble_gap_config_adv_data_raw() function, and its a blockin...
