chanList = channelList(mdfObj) % Channel table

data = read(mdfObj,chanList(2:3,:)); % i can read channel 2 and 3

data1 = read(mdfObj,chanList(5:11,:)); % I can read channel 5 to 11

But not channel 4 for some reason.

it is always giving me the error of result buffer too small.

Hey,

This seems to be a known issue with Vehicle Network Toolbox and is fixed in version R2019b Update 5 onwards.

The issue arises when trying to read MDF data from a channel that contains array greater than 256 bytes in size.

I would recommend you to kindly update the MATLAB version.

Thanks
