How to switch between task by receving data on BLE using FREERTOS?

Hi Everyone,

I have two task in which i am receving data from bluetooth and if i receive a particular hex value , i want a task(which is Toggling LED State) to run on the basis of the received data.

If there was no data received , then both task should run as per they are scheduled.

If i give a task delay of 2 minutes , the task switches from BLE to LED but , it runs continously there and BLE task also runs alongwith it. (NOT WHAT I WANT)

However if i give a task delay 1 minute , The task switches from BLE to LED and does not run continously.(EXPECTING SAME WITH 2 MINUTES OF TASK DELAY)

What i need is , its something like Immediate Task Switching. 

I have been trying to use xTaskAbortDelay function , the task does run from the input from bluetooth data, however , after that the LED task is running continously.

Does xTaskAbortDelay creating some problem here? Should I use something else to achieve the same functionality?

I am using SDK 15.0 With Segger Embedded Studio

Thanks
