Took 17.3 seconds to send 28757 bytes. this can be speed up reducing the latency though.

Tested the other way round (sent 29KB from Peripheral to Central) and I had no problems.

Thanks, chr

Sorry, I forgot to mention that so far I have been using 2 ios devices (iphone4s and ipad3), maybe with a proper BTLE module I would have less issues?

Cheers, chr

Hi guys, I manage to successfully pass data from the Central to the Peripheral and thanks to Khaos I have some ideas how the speed could be improved.

I was testing the solution passing 200 bytes spread across 10 [peripheral writeValue:chunk forCharacteristic:characteristic type:CBCharacteristicWriteWithResponse];
The communication was pretty solid and the speed acceptable (sometimes was taking just a couple of seconds)

Then I tried to increase the number of bytes passed to the order of tens of thousands and some problems appeared. Looks like the connection with the peripheral breaks after a bit. The maximum I managed to send "in one go" was 2KB. But most of the case it breaks after few hundreds.

I understand that what I am trying to do is not a canonical use case for the technology. But I wonder if it would still be possible to have a prolonged stable communication where the Central send a fair amount of data to the Peripheral or if I really do have to find a way to invert the roles.


Thanks for any opinion, chr
