I want to understand a little how a BLE module works. I have the following module ilt254s(the small version) but until now I was unable to communicate with it. Here is the datasheet. I want to be able to communicate with it using a MCU over UART. I have the following questions:
- Can I pair this with a laptop running windows 10? I have powered this up and I was expected to be discovered by the laptop but without success. Also, IOS and android phones and tablets were unable to discover it.
- When powered up the RX pin P02 is 0V and TX P03 is 0V as well. So I suppose this BLE is not using the UART. Do I need to program the chip(CC2540) in order to set UART active on P0? If yes how can I program it?
- How should I do in order to have it discovered and have it communicate with another MCU?
