I'm also using some software to test the data i'm sending is correct then using FC8 and ST-ARM to send the same data.
On serial monitor software i send an hex string (highlighted one is the manual string sent) the none highlighted is the string sent with FC8
As you see they are both the same (i get a response as expected on the software one and not as expected from the FC8 one)

Readable string sent from software as you can see all looks ok.

Readable string from FC8 and ST-ARM it looks to me that the data is missing or moved.

I have hardwired all connections just to be double sure, same issue.
Am i missing something simple or is it something else.
Thank you
