Hi all，i would like to ask a question about BLE MTU size on iphone 11.
At present ,i am developing a ble slave device . Sometimes,after the ble salve device sends a MTU request which value is 247 to iphone 11,the iphone 11 responds a packet of MTU which value is 23. MTU is too small for my ble slave device.
How to modify the MTU size as much as i expect? Can i resend a MTU witch value is 247 request to iPhone 11 for negotiating a new MTU size rathor than 23.

Here is today's example of Apple' anti-profanity filter gone mad. But this one has defeated me! Can anyone else guess what the "ble ***** device" is?
