iOS Question BleManager.WriteData

[pjrebordao]

Is there any fundamental difference in the usage of WriteData between B4A and B4I ?

I have an app running in B4A that transfers a few Kb of data between a device and phone.
The data is transfered in blocks of 512 bytes. After each block is received the phone increments a counter (a characteristic) and writes it back to the device.
This signals the device to prepare and send the next block.

Running in B4I, I only get the first block always.
I think the counter / characteristic is not being written back to the device and thus, it always sends the same one.

In the meantime I "discovered" WriteDataWithComplete and tested.

Makes no difference. Strangely I have a log statement inside the WriteComplete event and it never gets triggered...
BTW - is it WriteComplete or WriteCompleted ?

Don't assume that you can send more than 20 bytes on each call.

Actually, I'm just sending 1 byte - a counter

Many ways to see it in the IDE:
