pack binary trame

i receive a value from 7 sensors. After that i create a binary trame to send in sigfox. But i can't send the hexa value in sigfox so i try to use the pack function but i have a probleme with the fmt . i don't know which ftm choose. For the moment my code but it's not working because i receive only
class tools: def trame(capt1,capt2,capt3,capt4): result= (1 << 4) | 0001 result = (result << 10) | capt1 result = (result << 4 ) | 0010 result = (result << 10) | capt2 result = (result << 4 ) | 0011 result= (result << 12 ) | capt3 """result = (result << 4 ) | 0100 result= (result << 8 ) | capt4""" print(hex(result)) result=pack('hhl', result) return result
@quentho If you have three format specifiers in ustruct.pack(), you have to supply three values. The questions is, how you want to pack that into a message? And what is the value range of each sensor? And why do you add these 0001, 0010, 0011, 0100 (1,2,3,4) pattern into the string?
