This would be great to see incorporated into bluepy
as currently I actually need to segment some transfers and the subsequent overhead is slowing down the overall process.
Fear I cannot comment on the bluepy/bluepy-helper.c
changes in detail... as I've not worked with this myself; but wouldn't it be expected that there is a default MTU of 23 bytes? I don't seem to spot that in the code of this PR, but as said: noob here.
There are peripherals that initiate an MTU exchange request, but currently bluepy rejects the request and sends a not supported response.
These changes update the bluepy-helper to register for and handle the ATT_OP_MTU_REQ event. Additional changes were made to btle.py track the MTU and add the ability the to get the current value.
