Hi Guys,
I'd like to implement a counter on BLE peripheral that would be updated by BLE central devices as a voting system but this would require some synchronization that is not handled by the BLE itself, right?
For example, having a sticker device (Central/Master role) that contains the number of "likes" for a certain object, and having multiple smartphones (as client slaves) updating this counter would require the client to first read the counter value, incrementing it and then commanding a write operation to update it on the master, prone to race conditions errors.
Am I correct? Is there a way to increment a value without previously reading it?
Thanks
