my scenario is needs to to write the data simultaneously in that situtation I am getting the error "You must call endwrite before begin write" while after read the 1st data(response) from one bluetooth device.when i am writing the 2nd request to that particular device.
even i have created one event write callback() similar to that read callback() . in that event i have written end write method also. but it is not going to the end write method.
Please guide me. how to go in the right way.
