Part Number: LAUNCHXL-CC2650
Other Parts Discussed in Thread: CC2650,

Hi,

I want to communicated two CC2650LP board via BT and also connect a ST IoT Node board using BT.

Could any one tell me which example could help me?

Thank you

CC2650 only supports BLE. If another side only supports BT, it might not work.

Yes it supports BLE.
Which example of BLE could I use first to communicate two cc2650?

You can try simple_central and simple_peripheral examples to communicate two cc2650

The simple central and peripherial are for the cc2650em those still work for the LaunchXL?

Maybe you can run HostTest on one of LAUNCHXL-CC2650 and connect to PC to run BTool to act as BLE central. Then, run simple_peripheral example on another LAUNCHXL-CC2650 to join the one running BTool for communication.

Hey Angel,

As YiKai mentioned, there are multiple ways of getting started. You can start by using loading simple_peripheral on one board. On the second, you can load either Host Test or simple_central to connect to the peripheral device. There is a simple_central project example on our github here.

Take a look at the software developer's guide, located in the SDK_INSTALL_DIR > docs > SWRU393.

It may also help to review our SimpleLink Academy modules. Note, these modules are designed for the CC2640R2 devices (one of our newer devices), but should provide the insight needed to understand things on the CC2650.

The HostTest what does it do?

0 Ammar N over 7 years ago in reply to Angel Rodriguez43

The host test project is a way to send BLE specific commands (i.e. HCI commands) to a BLE device. It communicates with our Host Test software, located in the tools folder. With the host test software, you can configure your board to be a central or peripheral. It's mainly used to test your device quickly and send commands.

There's more information about this in the Software Developer's Guide (SWRU393).

Perfect Thanks!
in theory if I Run the simple_peripherial example and in the ST board I use the their GAP Central example they should be able to connect right?

Although I'm not familiar with the ST IOT board, you're on the right track! You should be able to connect with the other device as central.

In the Simple peripheral where is where it tries to connect to any network?

Connection is done by BLE Stack. Application only receives event in callback function.

Hey Angel,

Take a look at the BLE Software Developer's Guide located in the docs folder in your install directory of the BLE-STACK.

Additionally, you can take a look at the SimpleLink Academy modules to learn more. Please note that the modules were designed for a newer device, so the code may not directly translate. However, the concepts are the same.
