I want to analyze the Serial data (UART) through STM32F2 series board (Nucleo 144). How one can develop Network Tap or Packet analyzer using Nucleo 144 Board. Any rough idea is most welcomed. Thanks in advance

Thank you so much for Detail description. I will use it as reference while development. So first Task will be implementation of Functional TX & RX & then carry further. Abouth the sent API can you explain Little bit in Detail?? As link is created between API & HAL what exactly we Need to Change to establish it?

Regarding the API, I had a structure describing one SENT channel, however the channel needed an info about it's timer, so I needed to create a link between the SENT structure and HAL timer. Thus I expanded the timer structure by a pointer to some user data (in my case SENT channel structure) and the same in the SENT structure. So in case the timer interrupt has been generated, I had the information which sent channel it corresponds to and vice versa, when I worked with SENT channel, I had the information about the timer being used.

But this highly depends on your implementation, needs etc. Maybe you won't need it...
