nRF52840 BLE/NFC compliance testing, How to Change Channel & which tool to use ?

Question

Tx Radiated spurious emissions (1-18GHz): should be able to force the radio into a continuous transmit mode on a specific channel. The device should be transmitting with as high as duty cycle as possible on that the selected channels. Testing should be performed at the highest power setting allowed with below channels

2.402 GHz -Low Channel 
 2.442 GHz -Middle Channel 
 2.480 GHz High Channel

Receiver Spurious Emissions : should be able to force the radio into a continuous receive mode on a specified channel. Testing should be performed at the highest power setting allowed with below channels

2.402 GHz -Low Channel 
 2.442 GHz -Middle Channel 
 2.480 GHz High Channel

Hi, Shivbraham Singh said: as far as i understand from info-center that i have to create a project in uVision and load specific .c/.s file, compile it and generate hex file. once hex file ready program to our board. is it correct ? You don't have to make your own project, as the SDK includes project files for all example projects. Just open the existing radio test example in Keil and modify it as needed (most likely you only need to change the UART pins so that it match your HW). You can find the example project for Keil 5 under \examples\peripheral adio_test\pca10056\blank\arm5_no_packs\. To adapt to your HW, the easiest is to just replace the TX_PIN_NUMBER and RX_PIN_NUMBER defines in main c with the GPIO numbers of the pins you intent to use for UART during the test. As a side note you can also use the pre-compiled .hex file (radio_test_pca10056.hex) found under RF5_SDK_15.2.0_9412b96\examples\peripheral adio_test\hex\ if you have easy access to GPIO pin 6 and 8, which have been used for TX and RX respectively (see \components\boards\pca10056.h). Shivbraham Singh said: i need to compile whole SDK Program or which one ? You only need to compile the example project you are going to use (\examples\peripheral adio_test\pca10056\blank\arm5_no_packs\ in this case). Shivbraham Singh said: so connect both the board from Teraterm and Tx from one and validate Rx on another You connect the UART Rx and Tx pins to your PC and use the terminal emulator to control the test (send commands). )You do not need to connect the flow control pins as they are not used.)
