During CE certification, the lab measured the BLE TX power in DTM mode. at –20 &#176;C the power is 3–4 dB higher than at +25 &#176;C. Could you help to check if Nordic provide a way to compensate the TX poweren-USTelligent Community 13Wed, 21 Jan 2026 14:08:36 GMThttps://devzone.nordicsemi.com/thread/559278?ContentTypeID=1Wed, 21 Jan 2026 14:08:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0f1612da-a9eb-4955-aca0-50de0e81c9feSimonr<p>Hi</p> <p>We only do CE testing on room temperatures, so we do not have a way to compensate TX power over different temperatures I&#39;m afraid. Let me know if you would like our CE test reports and I will try to dig them out for you.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
