[chbot] Lazy and Blue tooth

[Daniel Powell]

While there are thousands of ways about doing the same thing....

I'm more familiar with the ESP32 platform, which has inbuilt Bluetooth, Wifi LR, and ESPNow LR (a Long Range point to point wifi freq network).
I'd simply use the ESP to host a website and use a phone browser to display the page or many pages.

Great tutorial here, although there are better gauge libraries for data logging/display.

Daniel.

The pinch-point for the project may be the phone/PC application. Phones tend to have BT built in, but how are you going to support BT on a PC (or do you mean a laptop ?).

Start off by writing a decent specification for the phone/PC end so you can clearly see what you are trying to achieve.

B4X may be useful start - multi-platform (phone, PC), free, and with support forums. There should be BT examples.

There is a low cost BT module called the HC05 - it might do what you want from the 328 end of things but may need another async port. Again, how is this going to connect ?

The ESP32 supports BT, so have you considered migrating from a 328 ?

Interested to know where you go with this project.
