 T1=[T1 count]
 datahex = sprintf('%02x', T1)
I don't know why output in that format],T1 is character

First, if there are spaces in your T1 string, get rid of them:
T1(T1 == ' ') = []; %remove spaces
For demo purpose:
T1 = char(randi(double(['0' '1']), 1, 128)); %random demo string of 128 '0' and '1'
Then, assuming that the length of T1 is a multiple of 8:
datahex = num2cell(lower(dec2hex(bin2dec(reshape(T1, [], 8)))), 2)'
Basically, reshape your string into columns of 8 characters. Convert each row from binary string to decimal number and then from decimal number to hexadecimal string. Optionally, convert to lowercase and cell array.
