Insufficient MTU: 253. #219
Comments
Hi @RoeeNadam - this is "standard behaviour" in a way. Usually it means you set the MTU higher than is supported by the current device / connection, so you need to set it to the value given with the error (it's an enum with an associated value, if memory serves right). You can check how this is handled in ImageManager:

I'm also seeing this error: But our MTU is set to 512...

@everuribe the error is in the logs, or DFU fails with this error? The error message might show up in the logs to "correct" the MTU down to the maximum length. As for that seven byte disparity, it could be many things. The McuMgrHeader is 7-8 bytes I think, could account for that, but don't hold me to it. Important thing: does DFU outright fail, or is it that you see this message on the logs? The latter is OK and expected behaviour. |
What can be the reason that I got this 253?
The write is successful but at a low rate of 0.3-0.4 kb/sec.
