   I ran in to this as well. My callback contained a function that gathered data from an external source which would run multiple times and crash the microcontroller. I must say I found it quite confusing that this was happening, although I have now had a practical education on one of the inner workings of BLE, which is a good thing I suppose!
   
   I think @rojer's idea of buffering the data is a good one. It would also be useful to be able to tell inside the callback function if it is being run for the first time in a long read, the last time, or somewhere in the middle. 
   This would allow the implementation of characteristics that iterate through a data structure, which would be useful in my application.
