hi all,
i need to send file to my peripheral and need data rate more than 32Kbps for it.
but , i can't do that .
Anyone have suggestion about to it.
First,
i have know that data type should be set "WriteWithOutResp."
and build gatt service on peripheral; so,iphone as the central.
then in peripheral setting the connect interval 20ms(min :10ms ; max :20ms)
when start send packet, every 10ms send one packet from iphone .
so, that only 16Kbps on it .
every connect interval has two packet to send.
how to Increase packet number between connect interval.?
Second ,
i rebuild the system for measure that, and change the devices role.
(iphone as gatts(peripheral) ; devices on gattc(central)).
Set "Notify" on characteristic at gatts ,to send other data type .
But, that can't do it also.
So, i think at iphone that have some limit on packet queue.
Platform:
iphone 4s
ios 8.2
