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).<br>
I'd simply use the ESP to host a website and use a phone browser to display the page or many pages.<br>
<br>
Great tutorial here, although there are better gauge libraries for data logging/display.<br>

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 ?).<br>
<br>
Start off by writing a decent specification for the phone/PC end so you can clearly see what you are trying to achieve.<br>
<br>
B4X may be useful start - multi-platform (phone, PC), free, and with support forums. There should be BT examples.<br>
<br>
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 ?<br>
<br>
The ESP32 supports BT, so have you considered migrating from a 328 ?<br>
<br>
Interested to know where you go with this project.<br>
