https://devzone.nordicsemi.com/f/nordic-q-a/82758/radio-current-consumptionHi,ALL: I use esb 2.4G liberary,and I found the same kind of produc build of nrf52840,it&#39;s radio current consumption is 1.2mA-1.3mA,how can it do it? My project is build of nrf52833,but it&#39;s radio current consumption is 5.9mA,how can I do to save theen-USTelligent Community 13Wed, 15 Dec 2021 11:27:04 GMThttps://devzone.nordicsemi.com/thread/343610?ContentTypeID=1Wed, 15 Dec 2021 11:27:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c9527d54-4b01-43b1-b81a-2ff1c7a20efbovrebekk<p>Hi&nbsp;</p> <p>The peak current consumption in TX or RX mode is around 6mA, that is correct, and you can&#39;t really reduce this significantly.&nbsp;</p> <p>The only way to get a lower average current consumption is to only enable the radio in short periods: Turn it on, send a packet, and then go back to sleep.&nbsp;</p> <p>On the receive side this is a bit more challenging. If you don&#39;t know when the packet from the TX will arrive you might need to keep the receiver running a lot of the time (increasing average current), or you have to find some way to synchronize the transmitter and receiver so that you can enable the receiver just before the packet is sent by the PTX, and turn it off immediately after.&nbsp;</p> <p>Best regards<br />Torbjørn</p><div style="clear:both;"></div>
