rf - PC to Arduino wireless link (low latency)



I want to build a robot car with an camera gimbal on top of it. This robot and gimbal should be controlled wireless by a gamepad and the head tracking of an Oculus Rift. As it is with the Oculus Rift, it has to have a low latency. Now I am searching a wireless solution to send the control bytes (about 5 bytes with max. 1000Hz) from a computer to an Arduino. The latency has to be as short as possible (1-3 ms). I already searched and I found these RF systems:



Is there a better solution? Or which of the RF systems above is the best for my case?



Answer



One of my co-worker suggested to use Bluetooth modules of the company u-blox, because they are low latency and also optimizable. I used two connectBlue OBS421I-26-0 and one connectBlue ACC-34. The ACC-34 is just a serial-to-USB adapter to connect the Bluetooth module with the stationary PC.

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
