How to fix issue with optimization screwing things up?

Jeff Lia

Other Parts Discussed in Thread: BLE-STACK

I'm using CC2650LP and the SimpleBLEPeripheral project example.

When I define the symbol PLUS_BROADCASTER (to enable advertisements while a device is connected), the build completes without errors, but when debugged on the device it no longer advertises at all.

I did find a workaround to this problem by simply lowering the optimization from level 4 down to 2 - Global Optimizations, but there has got to be a better solution than this.

Hi Jeff,

Which version of the TI ARM Compiler you are using? We have seen similar issues when compiling using TI ARM Compiler v16.6.0.

We recommend building BLE Stack v2.2 projects with TI ARM Compiler version 5.2.6. Refer to Section 2.6.3.2 “Installing a Specific TI ARM Compiler” in the BLE Software Developer's Guide (http://www.ti.com/lit/ug/swru393c/swru393c.pdf) for the procedure to install TI ARM Compiler version 5.2.6.

same as you, 16.6.0

I will give 5.2.6 a try, but as I recall there were issues with prior attempts. We'll see.

Hi Jeff,

BLE-Stack v2.2.0 has compatibility issues with TI ARM Compiler v16.6.0. We do not recommend using this compiler for any project that uses BLE-Stack v2.2.0.

We recommend using the TI ARM Compiler v5.2.6 because that is the version BLE-Stack v2.2.0 was tested and verified with. If you continue to run into issues after switching compilers, please let me know.
