nRF8001 What is the maximum data rate with peered device?

[Andrey]

As stated in standard the maximum data rate is 0.27Mbps. So is that is true for nRF8001 ??

I'm trying to use this as a solution for transmitting SteamVR positional information to a mobile device. In my 20 byte packet im packing the following:

• 0: Device ID
• 1-4: translation X float value
• 5-8: translation X float value
• 9-12: translation X float value

For a total of 13bytes out of the 20bytes allotted. My data is being fed from Serial USB and I'm transmitting this information to my mobile device as fast as I can. I've tried the follow:

1. Changing Serial baud rates
2. Setting Serial timeouts to low value
3. adjusting SPI clock dividers
4. commenting out code to buffer untransmitted data

All of which yielded roughly around 30fps of data received at the mobile device although my experience was running at 60+fps on my zenfone AR in a fairly empty VR scene.

I'm going to try to use wifi now. But it seems pretty consistent with the data provided above.
