Hello,  
I’m working on a Q2687 with the v7.46 firmware.

I have noticed that following functions do work in task 0, but do not work in other tasks :

- wip\_bearerOpen(…)
- wip\_FTPCreate(…)
- wip\_putFile(…)
- wip\_getFile(…)
- wip\_list(…)

However I do call the wip\_netInit() at the beginning of all my tasks.  
Is it normal and is there others functions like this ?  
Or do I make a mistake ?  
Thanh you.

See the section titled “Multitasking Feature” in the WIP User Guide…

I had read it but i misunderstood it.  
To summarize, bearer management function, and functions returning a wip\_channel\_t type, except functions creating sockets, must be call in task 0 context.  
It’s clear now, thank you.
