https://devzone.nordicsemi.com/f/nordic-q-a/63487/s113-vs-s140-tx-powerHi! We&#39;re running the NRF52840 chipset on a custom board. I&#39;ve recently switched from running the S140 softdevice to running S113 softdevice on our peripherals in order to save space. I&#39;m now trying to set the peripherals&#39; TX to the max possible, whichen-USTelligent Community 13Tue, 07 Jul 2020 20:03:40 GMThttps://devzone.nordicsemi.com/thread/258880?ContentTypeID=1Tue, 07 Jul 2020 20:03:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:11d335af-a1fb-44b7-81fe-1352fa290ad5J&#248;rgen Holmefjord<p>Hi,</p> <p>Unfortunately, +8 dBm is currently not supported in the s113 softdevice. We are aware of the issue and it may be fixed in a future release. Please contact your regional sales manager for details on roadmaps and future releases.</p> <p>There is no way to access the RADIO peripheral directly to override this. Access to the RADIO peripheral is controlled by the softdevice, writing any registers will cause an assert.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
