I am using nrf51822 chips and UART to communicate with my cellphone. I want to know if there are any ways to improve the sampling rate (reading and transmission) of measurement. I am doing the EEG stuff, so more date transitted is favorable. Thanks!

What "sampling rate" ?
Whether anything can be improved depends on where it's currently at - and we have no idea about that!
The nRF51822 Product Specification will tell you the capabilities of the chip.
Hi, Sampling rate relates to how many data collected in one second. More data collected in one second is preferred in my application.
Hi Jorgen,
Thanks for the good point. I guess you mean 1000/7.5*6=800. Could you provide some suggestions on how to modify the code? Appreciate it!
If you can post the project, I can try to help you. There are also many threads on DevZone related to the same question.
Hi,
Thanks for your suggestions. I will keep these in mind. Do you mean that the dongle used with the computer has a better throughput?

If you use the Nordic Dongle, the BLE code is running on the dongle itself - so it is not subject to any restrictions that the host OS might impose.
The same would apply to using a Nordic Dev Kit .
Or other custom board ...
Got you. I will give it a try.
