Unable to sync with device error when porting rosserial to STM32F7 Discovery

I'm trying to use rosserial on the STM32F7 and I've been following some tutorials online namely this, this and also this as I'm a Keil guy.

Unfortunately, I run into the 

Unable to sync with device; possible link problem or link software version mismatch such as hydro rosserial_python with groovy Arduino

error. I've used tested with multiple UART ports and also used about 4 different timers on the board but I'm still running into the same issue.

Could anyone possibly throw some pointers my way?

Have you looked into micro-ros? I always had issues with rosserial as well....and thats why I am very excited about the progress micro-ros is making.

I ended up just streaming my data over UART and reconstructing it in ROS. Overhead was probably lower as well.
