https://devzone.nordicsemi.com/f/nordic-q-a/90014/maximum-supported-mtu-size-nrf52810Hello, I saw in the documentation for the softdevice s132 v5.10 (which is for production use now), I saw it supports changeable MTU. I have searched for the maximum supported MTU size in the documentation but found none.

Any idea why?&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/377160?ContentTypeID=1Fri, 15 Jul 2022 10:46:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d92f3a9f-f0e7-43be-b811-908c375d9691Kenneth<p>There is no limit per the spec on how high the ATT MTU value can be, but the maximum length of an attribute value is per spec 512 octets. The Softdevices supports this value.</p> <p>Kenneth</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/377042?ContentTypeID=1Thu, 14 Jul 2022 19:15:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f87ac798-53a0-42b3-ac1f-627be7456d37maher<p>The question is meant for Attribute MTU size, the nrf52810 should act as a server that host some characteristics.&nbsp;</p><div style="clear:both;"></div>
