Old thread, but I just bumped into this myself so want to resurrect it. Current api makes it very difficult to implement a long characteristic that changes frequently (e.g. time- or sensor-based reading, or including a random component). In the case where mtu exchange fails or does not complete

Question regarding exchanging long characteristic values over BLE

Hi All, So I'm trying to understand who is responsible for handling chunking the characteristic value in case the MTU of the connection is smaller than the characters ic value size. So for example, if I have a characteristic value of size 100B. When an iOS App connects to my device and reads the
