255-byte MTU with iPhones
Hey guys,
I was wondering whether any of y'all had success connecting nimBLE stack to
an iPhone with 255-byte MTU size as per Bluetooth 4.2 spec.
There's prolly no point in trying anything before iPhone 7 because they
might not have a 4.2 chip. Any got a chance to give that a spin with iPhone
7? Have any throughput numbers you can share?
Jitesh

I haven't tried it myself yet. Thought I'll ask around first in case
someone ran the experiment already.

Hi Jitesh,
I don't believe I've tried an MTU of 255 with an iPhone. What issue
are you seeing?
Thanks,
Chris

I have not tried it myself; I cannot recall if Chris tried it. He is currently on a plane but will hopefully chime in on this soon.
We do not have iphone throughput numbers but we have throughput numbers that we achieved using two nimble devices: we achieved single connection LL throughput approaching 800 kbps.
