CSR 4.0 UART NRF51 connection?

[Sri_guy]

Hi,

I programmed my NRF51 to read ADC samples and I trying to transmit the information to a dongle. So far I have been able to send the hexadecimal values of the recorded voltage to my iphone using the Nordic UART Service and the Bluefruit App, but I was wondering if there was a way to send the information to a CSR 4.0 dongle.

Thanks.

what's a CSR 4.0 dongle? If it's programmable then you'll have to write code for it to talk Nordic UART protocol, if it's not programmable you'll have to write code on the nRF51 to communicate with it in one of the protocols it understands and not use the Nordic UART service.

I am using the CSR 8510 found here: www.adafruit.com/.../1327. I'm don't believe its programmable. How would I know which protocol is compatible exactly? Is there a universal one by chance in sdk im not seeing?

Thanks

it's a generic dongle which is programmed to do generic BLE things. You communicate with it over HCI. There is no protocol in the SDK because the dongle is just a generic communications channel. If you look at Adafruit's raspberry Pi example you'll see how they use it in a simple case.

You'll need to write some application code for whatever platform you're using to implement the whole protocol. The dongle is just like having a bluetooth-enabled laptop, if you want to use bluetooth on it, you need to write code.
