Hi TI Sirs,

I used the sample program below and added the pthread function, but the following error occurred after executing the compilation. Please help confirm how to improve it, thank you

Hi Amos,

Have you added Settings = xdc.useModule('ti.sysbios.posix.Settings'); to simple_peripheral_app.cfg? https://e2e.ti.com/f/1/t/589588
Any why are you trying to use pthread instead of Task.h like SimplePeripheral_createTask? https://e2e.ti.com/f/1/t/786714

Ryan

Hi Ryan,

Thanks for your help, I can test normally.
The different examples provided by TI use pthread and task.
As far as I know, the purpose of the two should be the same.
May I ask the reason why pthread is not recommended? Is there any risk?

BR,
Amos

There should not be any risk, it is just not recommended since BLE projects already use the higher-level Task module and thus would be more consistent and easier to reference across the project. Here is the TI-POSIX User's Guide for more information.
