https://devzone.nordicsemi.com/f/nordic-q-a/12711/standard-att-commands-nrf51822Hi, To measure the transmitted RF power (to reach EN 300 328) we Need some ATT commands to set fix channel and maximal output power. In additional we test the EN 55022:2010. The test Labs ask for ATT Commands to set the Chip in the right mode. en-USTelligent Community 13Wed, 23 Mar 2016 10:07:44 GMThttps://devzone.nordicsemi.com/thread/48274?ContentTypeID=1Wed, 23 Mar 2016 10:07:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1715632c-35d7-47fe-bb1f-143925ab4d80Hung Bui<p>Hi Philipe,</p> <p>We don&#39;t have an example that the nRF51 takes ATT commands to do configuration. But we provide the radio_test example in the NRF5 SDK that you can use UART to set the configuration. Please find the radio_test project in SDK folder\examples\peripheral</p><div style="clear:both;"></div>
