Maximum data length to send

[bishop]

Hello! What is maximum number of bytes can I send from Central/Peripheral to Peripheral/Central device in one packet? Can I send more than 200 bytes in one packet? I want to implement something like TCP/IP connection with confirmation.

@Bishop: The maximum payload length for a packet with our stack is 20 bytes. Attribute's value that is longer than 20 bytes can be transmitted using queued write or read blob. But the payload on each packet is max 20 bytes.

Note that you can use write with response and/or indication if you need acknowledgment from the peer device.
