The 'Evt_Blue_Gatt_Attribute_modified' isn't called (is slow) for each received ble message (change of characteristics message)?
I am trying to do a file transfer over ble, using 20 byte characteristics writes. I did notice that, following a write command for characteristic, the resultant aci_gatt_attribute_modified_event() doesnt get called quick enough to process the next incoming messages. (bluenrg1_events.h version V1.0.0)
Herein I saw the following times
the response for the write message takes 1-3 ms to me sent over to the receiver
the consequent procedure complete call takes over 10- 20 ms to be received by the receiver.
The blunrg1 is running at 32000000Hz. I have the following svc & characteristics details
services added 4, total characteristics -13 (1+4+4+4).
Also, I timed the function in the main loop running the BTLE_StackTick() & APP_Tick() and their time utilization seems to me less than a 1ms.
Is there any way the responsiveness if the stack could be increased/ optimized?
Please let me know if you have any questions,
