CC2650: Understanding basic libraries use & integration with BLE Stack

Justin Reina89

Part Number: CC2650


I am having the worst time making use of the following routines in my BLE Stack firmware use on the CC2650 Launchpad:

Issue

When some of the routines below are used in my BLE Stack firmware it causes UART_write() to hang!

Routines

  • sprintf()
  • strcpy()
  • strlen()

Question

  • why are these causing hangs of UART_write(), and how to resolve?

I was traversing down the path of manual implementation of each routine for resolution, but this methodology is as buggy as heck. I need to first understand what's going on, thoughts?

    Hello Justin,

    From your post I can't determine why you see the hang. However, I suggest looking at Project Zero in SimpleLink Academy - this has a functioning UART logging implementation.
