LAUNCHXL-CC2640R2: UART

GreenAndGrey

Part Number: LAUNCHXL-CC2640R2
Other Parts Discussed in Thread: CC2650, CC2640R2F, , CC2650STK

I have 2 CC2640R2Fs- one on the launchpad, and another experimentally replacing the CC2650 on a CC2650Sensortag board with the debug DevPack.

I am running the Simple Peripheral BLE example, and when I run the code on the launchpad it works well, and I can see UART messages. However, when I run the same code on the Sensortag board, I'm able to see the device advertising but I don't see any UART messages. The CC2640R2F and the CC2650 are pin compatible so my second setup with the Sensortag must also work - what am I missing?

Hi again GreenAndGrey,

Correct me if I am wrong. I'm a bit confused on your setup.
So you're using two CC2640R2F LaunchPads. One running the simple_peripheral example. The other is running a project that was made for a CC2650 Sensortag?

I have a legacy Sensortag project with CC2650 that I'm experimenting with to move it to the CC2640R2F platform.

My experiment is that I'm using 2 CC2640R2F MCUs - one natively in the launchpad (LAUNCHXL-CC2640R2), and the other one replacing the CC2650 MCU in the Sensortag (CC2650STK) kit since the CC2650 and CC2640R2F are pin compatible. The Simple peripheral example UART runs on the Launchpad, but not the Sensortag board with the CC2640R2F.

Do you mean you replace CC2650 on CZc2650STK with CC2640R2? If so, original SensorTag example won’t be able to run on it.

Yes, I replaced it but I'm running the Simple peripheral example from the CC2640R2 SDK on it.

Do you change pin settings according to CC2650STK schematics?

Hey GreenAndGrey,

Have you been able to resolve this by adjusting the board file accordingly to the CC2650STK?

I have not. Is there a guide to do this?

Hi GreenAndGrey,

Please refer to the attachment

3731.CC2650STK.h

What about the corresponding .c file?
So far, I've created a new folder CC2650STK in <TI_INSTALL>\simplelink_cc2640r2_sdk_1_50_00_58\source\ti\blestack\target and dropped the .h file there
Modified the Board.c to include the CC2650STK.h file

I'm working through the instructions at dev.ti.com/.../custom-hardware.html and will report my progress back. Thank you for the help so far!

Here's my progress
- I obtained the file CC2650STK.c from the BLE SDK 2.1 install (that's the version I had for my original Sensortag project)
- Defined a new preprocessor symbol for the board, and I'm using it to point to the new board files
- Working through a lot of compile errors for redefinitions of macros between the newly added CC2650STK.h and Board.h;

Hey GreenAndGrey,

How are you doing with this? So you're essentially trying to port over the functionality of the SensorTag project over to the CC2640R2F?
Were you able to work through the compilation errors, redefinitions and the switch to a different board file?

I took a step back and went to the Simple peripheral on-chip OAD example instead since we'll need this feature as well. And I am porting the board-level changes into that project instead.

Hi GreenAndGrey,

I ported the CC2650 SensorTag to CC2640R2F Launchpad. See, blog post below with github link to the code. It is based from CC2640R2F SDK v1.30. So for it to work for SDK v1.50 you need to migrate it.

Hey kel,

Thanks for providing this very useful resource. I will be marking your post as a possible resolution to this.

I corrected some typo error from my earlier reply in BOLD letters.

Thank you both for your excellent help. I think I have most of what I need ported over.
Kel, I did look over your repo for ideas and leads when I was starting off!

Hi,

The BOOSTXL-SENSORS was not available when I did that project. If you want to interface the BOOSTXL-SENSORS to CC2640R2F Launchpad, you can get code library at Sensor Actuator Plugin SDK.
