CCS/CC256XCQFN-EM: Unable to pair with Bluetopia demo on MSP430

Part Number: CC256XCQFN-EM
Other Parts Discussed in Thread: CC2564C

Tool/software: Code Composer Studio

Hi TI community,

I am trying to run simple BT demo according to: http://processors.wiki.ti.com/index.php/CC256x_MSP430_TI_Bluetooth_Stack#Demos

I managed to establish connection via Putty as shown below (two separete demos: SPP and A3DP):

Unfortunately I'm unable to detect MSP from any BT device. I have two MSP-EXP430F5438 boards with CC256XCQFN-EM modules and cannot discover neither of them.

On the other hand, MSPs are able to list BT devices without a problem, but apperently not vice versa.

Sometimes one of the boards shows up for short period of time, which enables initialization of pairing procedure, but disappears before i can pair the devices.

Details:

  • 2x MSP-EXP430F5438
  • 2x CC256XCQFN-EM
  • CCS6
  • compiler: TI v4.4.8
  • output: legacy OFF
  • using "__SUPPORT_CC256XB_PATCH__"

Any suggestions how to fix this issue or what could cause this behaviour?

Kind regards

Jakub
