Discover wifi module sending data problem in STM32F4DISCOVERY Expansion Boards

Posted by demure Jul 22, 2014

I changed discover wifi STM32F4 code. When i send 'y' character or 's' or etc. it hasn't problem. But when i send any character and if i wait response it has problem. it works 3 or 4 times after that it has stack overflow ( I think) problem.

After that module not work until reset.

If anybody has an idea, i can share code.@

Thnaks.
