Baud rate on RX-28, RX-64

Now my robot use 16 of RX-28 and 2 of RX-64 in the same wiring (16V)
I want to read some internal sensor value in each motor. I don't know which baud rate is the best. Because, now, I use 115200 to communicate with 20 servo motors. It's quite slowly response and the return packet is drop, when I tried to write command and read data.

Thank you

It is common to use the maximum speed of 1Mbps.

If you have problems at 115K, you need to address that first.

What controller are you using ?

USB2Dynamixel works fine at 1Mbps.

To get best performance make sure latency on CPU USB driver is set to 1 millisec, and the servo return delays are all set as short as possible.
