Is there a way to increase BTLE max chunk size for writing value i.e. CBCentral maximumUpdateValueLength?

I'm trying to send 2k of data from my iPhone configured as a BTLE peripheral to my iPad. Right now the chunk size as dictated by CBCental::maximumUpdateValueLength is a mere 74 meaning it takes ~1s for transfering the payload. I'm wondering whether anyone knows a way of increasing this value (indirectly I presume)? Maybe some configurable somewhere telling the iPhone its ok to use more power for BTLE?

No, there is not. – Paulw11 Mar 21 '17 at 19:37
You should have more than 74 bytes according to [this](http://stackoverflow.com/questions/41977767/iosble-get-negotiate-mtu/42336001#42336001) – Paulw11 Mar 21 '17 at 19:44
Hmmm. I'm using an iPod touch 5th gen. Maybe that's lower?? – Hari Honor Mar 23 '17 at 10:53
