https://devzone.nordicsemi.com/f/nordic-q-a/76814/constant-tx-power-without-dtmHi! We&#39;re working on a testing Jig which should test our units in production. One of the tests I&#39;d like to make, is measure the current draw on TX at max (8dBm). I would like to do this without flashing my devices with a different firmware than theen-USTelligent Community 13Mon, 28 Jun 2021 11:20:52 GMThttps://devzone.nordicsemi.com/thread/317447?ContentTypeID=1Mon, 28 Jun 2021 11:20:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:272a8387-690d-42d6-9015-dd7eb11673b2Kenneth<p>Hi,</p> <p>The softdevice does not have such functionality. I recommend to add a test pin, and at startup the application can check the level of the test pin to decide if it should run application or production test. Then you can run the radio test or DTM if the test pin for instance is high. This will increase the size of the firmware a bit, but I would not expect dramatically.
