One of the rules is there can only be x dBm difference from device to device. I think each device needs toen-USTelligent Community 13Thu, 07 Jul 2016 13:08:58 GMThttps://devzone.nordicsemi.com/thread/57207?ContentTypeID=1Thu, 07 Jul 2016 13:08:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:df84449d-6f4a-401d-b789-edd8df1b7d44CurtisHx<p>That is for FCC Part 15 Certification. Truth be told, I&#39;m not entirely sure what the FCC requires, but we had to work hard on past projects to ensure consistent output power from device to device. I think we can make 1dBm steps work, but I was curious if it was possible to get finer output power control.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/57206?ContentTypeID=1Thu, 07 Jul 2016 12:41:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3f5606c4-ecb1-46de-8b74-fc13443d7d7b&#216;yvind Karlsen<p>Hi,</p> <p>It is not possible to set the power in +/- 0.1 dBm steps.</p> <p>We have not encountered any such regulation, where did you find this?
