Basically I'm trying to feed in High low signals into the TX pin of a HM-10 BLE module and display it as a graph, similar to how an oscilloscope would, or possibly just have a threshold where it would change some indicator on a web app. Chrome allows you to use bluetooth if you type in

chrome://flags/#enable-experimental-web-platform-features

to the search bar and enable it, and applications exist to connect to them such as

https://loginov-rocks.github.io/Web-Bluetooth-Terminal/

https://github.com/ErniW/Web-Bluetooth-and-HM-10-module-for-Arduino

but they seem to be more focused on sending messages rather than raw 1 and 0 voltage input.

So.. How would one go about just receiving the data?

Thank you for your time and help if you can share some wisdom.

  • \$\begingroup\$ Well, maybe. I was able to just feed in raw voltage to a kcx_bt_emitter have it connect to a bluetooth speaker, and have it output noise if voltage is high/low. So it seems like it would be possible to just send the high low signals. \$\endgroup\$

  • \$\begingroup\$ Bluetooth is a digital connection, not analog ... the data is a multiple of bytes \$\endgroup\$

  • \$\begingroup\$ Seems like the best option would be to slap a micro controller in the middle and have it turn high low to transmittable data \$\endgroup\$
