CCS/EK-TM4C123GXL: TM4C123G LaunchPad and CC2650 Module

Ai,

I will assign someone to help you.

Thanks,

Luis

Hi Alec,

I already got my MSP432. Do you have any source, documents or tutorial I can learn to connect msp432p401r and BOOSTXL-CC2650MA via bluetooth. 

Sincerely, 

Hi Alec,

Thanks for your help a lot. 

Due to some problems I can't post a new question. I've done one simple project relating to MSP432p401r and CC2650 Module via bluetooth but it does not work. I hope you can me figure it out. 

First I modify code from UART PC Echo 12MHz example. I use UART0 for pin 1.1 and 1.3 and communicating via USB and Tera Term. When I type 'r' it turns LED Red, 'b' for LED Blue, and 'g' for LED Green. 

Then, I want to connect MSP432p401r and CC2650 Module via Bluetooth. I choose UART2 for pin 3.2 and 3.3. I connect TX (CC2650 Module) to P3.2, RX(CC2650 Module) to P3.3, GND to GND and 3.3V to 3.3V. Total is 4 wires. But I can't find Bluetooth signal in Laptop or TI App or LightBlue App on Phone.

Here is my code.

Sincerely, 

Hi Ai,

I would highly recommend that you base your project off of one of the sample projects included in the BLE plugin. There is a lot of configuration involved with BLE, so it will save you a lot of time if you reuse the BLE code included in our examples. Read through the description of each of the descriptions for our examples and see which one is most similar to what you are looking to accomplish. Project Zero is usually a good starting point for most use cases.

Best Regards,
Alec
