Reading data from BLEv4 (HC08)
I've got a problem with HC08 module (BLE v4) understanding. I know that BLE module send some data called services and services have got characteristics but in fact how it works? I connected my module to the development board using UART. I'm using LightBLue Explorer app for android. When I connect to the HC08 module I see 5 characteristics and "Key Press State" service (some of them are writable/readable or them support notifications). On the other side I'm sending "Hello World" with 1s period with UART on microcontroller. Where and when am I able to see this message? Should I see characteristic change or something? (Now I don't see anything interesting). The second thing is second direction (from the android to the microcontroller). When I enter some text in the app how response to the controller should work? Thanks for your replies.
