Manipulating a float to unsigned into and back

Question

I am currently working in C with a microcontroller and in order to transmit a reading over Bluetooth I have to send it as a uint8. The reading is currently in the form of a float. I've been trying to think of how to do this and then be able to convert it back to a float on the reciever end but have no ideas. I'm limited because I can't utilize a custom structure or anything because it has to be in a uint8 to transmit.

Any suggestions?

I have tried a couple things but none have gotten very far so I don't have much to show for it

Answer 1

Any type in C can be traversed using character pointers and on all sensible compilers, uint8_t is a character type. For example:

const uint8_t* ptr = (const uint8_t*)&some_var;
for(size_t i=0; i<sizeof(some_var); i++)
{
  send_byte(ptr[i]);
} 

Keep in mind however that your CPU endianess might not match network endianess, in which case you need to swap the byte order before sending.
