I get soft reset when MTU is bigger than 65

Stefan

Hello!

I am trying to increase the MTU size to get higher speeds. When I increase the MTU above 65 the application locks/software reset when doing transfer. Up to 65 it works. I have increased RAM memory for SoftDevice a lot. No difference. I check the return value of softdevice_enable(). Always zero. I have not enabled DLE.

65 sounds awfully close to 64, but it is still a bit strange value.

Any hints or tips would be appreciated

    Hi Sigurd,

    your debug suggestion worked. I have now found that the error comes from softdevice_handler.c line 187 and I get NRF_ERROR_DATA_SIZE (error code 12). I do not understand why.

    I will close this and open a new question, thanks for the help!
