nRF51822 channel frequency

[Shaun]

Hi,

I am using nRF51822 BLE nano with mbed IDE. I tried to set channel so that i can achieve the desired frequency for FCC testing i.e. 2402MHz,2441MHz and 2480MHz .I am using radio_test example from nordic but the response is like:

Channel 0 set Frequency 2397.11 MHz,
Channel 1 set Frequency 2400.69 MHz,
Channel 2 set Frequency 2400.69 MHz,
Channel 3 set Frequency 2400.69 MHz,
Channel 4 set Frequency 2404.26 MHz,
Channel 5 set Frequency 2404.266 MHz,
Channel 6 set Frequency 2404.266 MHz,
Channel 7 set Frequency 2404.266 MHz,
Channel 8 set Frequency 2407.843 MHz,
Channel 9 set Frequency 2407.843 MHz,
Channel 10 set Frequency 2407.843 MHz,
Channel 11 set Frequency 2407.843 MHz,
Channel 12 set Frequency 2411.42 MHz

Which seem to be incorrect. I think each channel should set different frequency.

How can i fix this and get the desired frequencies ?

Thanks Shaun

Hi Shaun,

There must be something wrong here. The frequency should be: frequency = 2400 + channel(MHz)

When you flash a BLE application, do you have a good link ?
