Hi

What and all will be the effect of changing the baudrate from 3000000 to 115200?? Is there any reference available on this topic?

Suggestions appreciated.

When changing the baudrate from 3M to 115k the HPEV reader could, depending on the BLF and coding configuration, inventory more TAG data than it can be forwarded to the host system. When the internal TAG buffer FIFO of 64 TAGs is full the FW drops received data until the FIFO has again free space.

Nevertheless, it is possible to switch the BR to 115k. See main.c were the BR is adjusted.
