Hello,  
I try to convert a buffer with no luck …  
The msg.payload is:  
buffer[2]raw  
0: 0xc  
1: 0xda  
And the conversion expected is:  
24,84  
Somebody can help me?  
Thanks  
Ben

Hi @BQ06

Do you have any more information on how that buffer is encoded? Without more detail we’d largely be guessing.
