MATLAB: Convert binary file from hex little endian to decimal

Question

Hi- my first post so go easy.

I get data from a sensor via a RockBlock Iridium Modem. The data come in 50 byte messages. I get an email with the data in Hex (little endian) – here is an example

85cd0a0084a7f6ff884027000b27e5cc0a0031a6f6ff885026000d427acc0a0096a4f6ff886026000c322900605a0002003c

I also get a binary file with the data.

I would like to read the binary file and decode it in matlab. I tried to attach my binary data file but it was not a supported file format so I've included a link to it here

For example, the first 8 bytes correspond to the latitude. I need to convert from little endian to big endian and then to decimal.

Answer 1

So, I think I figured it out.

fname = '300434063383360-608.bin';

fid = fopen(fname);

A = fread(fid);

H = lower(dec2hex(A));

hxstr = [];

for i = 1:length(H)

hxstr = [hxstr H(i,:)];

end

fclose(fid);
