Unable to run HTTP GET request within a GPIO interrupt on CC3200 launchpad

tdao

Hi,

I'm trying to do a small HTTP GET request to a web page and receive about 100 bytes back within a GPIO interrupt handler (by pressing SW2 on the launchpad). However the program hangs whenever it hits this code inside the handler. The same code runs fine on the main thread. Is this expected or do I need to do something else to make it work?

Thanks.

Hi Tung,

Are you calling any of the simple link host driver APIs from the interrupt handler? If yes, then you should not call them in the async event handler or from the interrupt context.

Hi Raghavendra, I think that was the problem. I was trying to do GET command within an interrupt handler. I have changed this to setting a flag in the interrupt handler, and then do GET on the main thread. And this is working fine.
