Starterware/BOOSTXL-CC2650MA: Temperature Sensor Broadcast

Part Number: BOOSTXL-CC2650MA
Other Parts Discussed in Thread: CC2650

Tool/software: Starterware

I have been trying to implement the Temperature Sensor Broadcast example on the MSP432P401R Launchpad/CC2650 Booster Module while trying to learn how to send sensor data over Bluetooth. However, this example imported from the Resource Explorer through CCS does not seem to be working properly for me. Although it builds with no errors, when running it on the device(s) the Bluetooth Connection is never advertised and the output to the console stops at "Done!" where I should be seeing "State set to idle."

I have ran and used the Project Zero example successfully which leads me to believe it is not a hardware issue.

Note: I am trying to implement a very similar program for my senior design project so I believe getting this example to work will be especially helpful, any other guidance/resources on learning this subject would be great.

Thanks for any help!

Hello Vincent,

I suspect that you might not be using the latest SNP image. This is the the image that resides on the CC2650 that acts as the "black box" BLE radio that the MSP432 communicates with. In the newer version of the SNP image we added some support where additional "format descriptors" are supported. This would explain why ProjectZero works versus the temperature sensor example as ProjectZero does not use the new descriptors.

In the user's guide we detail how to update the SNP image in multiple ways:

http://dev.ti.com/tirex/content/simplelink_msp432_sdk_bluetooth_plugin_1_20_00_42/docs/users_guide_simplelink_msp432_sdk_plugin.html#generating-new-snp-image-firmware-upgrades

If you have ProjectZero already working though I'd recommend running ProjectZero and then holding down S1 and S2 on the LaunchPad until the LED turns white. This will force an update of the CC2650's firmware via the bootloader and should solve the problem that you are having with the temperature sensor broadcast.

Best Regards,
