Hi Trivenu,

You can set the ATT MTU size to 512 byte, then the maximum number of bytes is 509.

You can find more details here: Maximum Packet Size According to MTU - KBA203312

Owen

Note: Both the phone and the device need to agree on using the larger MTU to function properly. Technically the central-side will control the MTU size, but if the peripheral never uses it, then it is as good as not being enabled, and I'm unaware of how the peripheral will handle larger-than-MTU packets received from the central-side.
