D doodooronron Member Licensed User Sep 29, 2020 #1 I see that the BLE data packet size can be increased in Android by use of manager.RequestMtu(n) but cannot find it in the iOS libraries and get an error when I try to use it in code. Is this instruction implemented in iOS yet? If not, is there any more elegant way round it than adding incoming data to a buffer then parsing byte-by-byte?

Erel B4X founder Staff member Licensed User Longtime User Sep 29, 2020 #2 It looks like it is fixed on about 158 bytes. There is no similar API in iOS. Tip: use B4XBytesBuilder for the buffer (B4XCollections library). Upvote 0

Do you mean the iOS data packet size limit is 158 bytes? If so, that would be plenty for my application. Upvote 0

D doodooronron Member Licensed User Sep 29, 2020 #5 Yes, looks like it's mercifully bigger than the paltry 20 bytes standard of Android. Found this: " iPhone iOS 8 has a maximum MTU size of 135 bytes, iOS 9 158 bytes and iOS 10 185 bytes" on https://devzone.nordicsemi.com/f/nordic-q-a/44825/ios-mtu-size-why-only-185-bytes It will save a ton of work if that's the case. Thanks again Upvote 0
