BLE is not about doing a continuous stream of data. Its more of a publish-subscribe (or event-based) mechanism, because this is much more power-efficient. The module you used was not a BLE module, but a conventional Bluetooth module.
That said, in the 100 BLE projects list there is an example that simulates a serial port of BLE.
Hello Hli, you are correct. I used a conventional Bluetooth module before.
I installed the project you suggested and I am able to send data from the phone app CySmart to PC, but not the other way around.
I installed a third party Hyperterminal type of app, but was not even able to pair.
Any thoughts on these issues?
This sample project assumed that you program both sides of the connection. In the example I think this was the BLE module and the CySmart dongle. If you want to use some else on your PC side, then it needs to be programmed accordingly (the serial-over-BLE profile is custom and not a standard one).
