i am currently developing a small HTTP Server, which has to deliver some big files (over max. heap-size), so i have to stream them chunkwise from FLASH.
To determine when the next chunk can be sent, i have to release my semaphore in the espconn-sent callback.
But this didn't work.... it wont be released.
So i was wondering, if the esp-callbacks might be interrupt service routines ?
Thank you in advance!
