I'm trying to receive data from a sensor in real time. the problem is the communication protocol is entirely binary lengths varying from 3 to 20+ bytes (in one frame).
I tried two use methods:
converting my hex value into text (equivalent ascii) and sending the string. the problem is 00 is represented as the nul char and cuts my string (sending everything before the first 00).
I then tried to use the binary fwrite command, but i'm limited to 8,16,32,64 bits where as i need an arbitrary number (such as 24).
I also tried cutting my data into multiple (8bit/16bit/32bit) segments and sending them one after another, but that also doesn't work. it needs to all go at the same time.
As an example, i'd like to send '0x201000' and '0x2005503C280000' in one go.
Does anyone have any idea on how to tackle this problem?
