Thanks for reporting this. I wonder if it is related to this post:

Anyway, we'll have a look and get this fixed.

I think that filter should work. The Service and Characteristic values needs to be correct for your ESP32 device. If you call "RequestDevice", the browser should ask to connect to your device. Once connected, the "OnValueChanged" macro should be called when the data for that Char...

Yes, that's the component. But a slightly newer version is attached here (this one has a proper icon). The complication is the "filter" expression. Due to domain origin issues in (most?) browsers, this needs to reference the actual device being connected to. There are examples in the toolt...

BTW, a beta version of the BLE Web Developer component was posted by Ben here:

Great news, Daniel. Thanks for letting us know.

I'm glad my input was of some small use.

I have made a Web Developer component, but it is currently unreleased and needs a little more work. I'll look into it again and see if we can get something out soon.

I've not make a bootloader for this type of device, but I did a quick search and found this which may be of help: https://support.microchip.com/s/article/PIC24-dsPIC33-bootloaders---How-to-Create-and-Verify-a-Custom-Linker-File You probably don't need to create a linker script that deals with both t...

Do you know what specific source code it being compiled to live within the bootloader area? Or is the problem just that the IVT code is not being placed into the relocated area? Or is it something else? It might help to create a *very* simple example of the issue in MPLAB and replicate it in Flowcod...

Further to @chipfryer27's suggestion, there is more info about the Supplementary Code feature in the wiki and there are many posts on the forum that discuss it too. For example, see here:

Also, please post your project as that will allow us to see what you have tried.
