3 Bluetooth: MTU Update
9 Question: What do I have to do to update my ATT MTU?
11 | Answer: To get an ATT MTU of x octets, do the following:
24 Answer: Yes. [#mtu_exchange]_ The Bluetooth specification mandates a symmetric MTU for ATT.
29 This sample demonstrates the exchange of MTU between two devices to allow a
31 Updating the MTU can be useful to send bigger packets and so have a better
35 update their MTU. The MTU is not a negotiated value, the client and the server
36 will exchange their MTUs and choose the minimum of the two. Thus the two MTU can
37 be set to a different value, but the MTU of the server must be greater or equal
38 to the MTU of the client.
40 According to the Bluetooth specification, [#mtu]_ MTU is the maximum size of
45 The Kconfig symbol used to configure the size of the TX MTU is
47 the size of the RX MTU, because Zephyr uses a buffer pool for ACL RX buffers
49 The L2CAP RX MTU is defined as the maximum size of ACL RX buffers minus the
53 The resulting L2CAP RX MTU will be the value of this Kconfig symbol minus the
81 and send his MTU to the other device. If the MTU exchange succeeds, the central
