https://devzone.nordicsemi.com/f/nordic-q-a/35604/optimization-of-the-current-consumption-of-the-central-deviceHello everybody, I am using central device with SDK14.2 and S132. In a central application, the operation sequence is as follows: * Buttons pressed and scan started * Connect and LED on if the desired peripheral device is found * Send a nus_data withen-USTelligent Community 13Tue, 26 Jun 2018 12:05:25 GMThttps://devzone.nordicsemi.com/thread/137668?ContentTypeID=1Tue, 26 Jun 2018 12:05:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a4218971-44cc-4c44-b24e-774cd3a96781Stian R&#248;ed Hafskjold<p>Yes, if you are running radio the RX peak currents will be about 6.5mA @3V. The TX peak currents can be reduced if you reduce the TX power (dBm). If you increase the voltage the current will go down (but not the power (watt))</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/137644?ContentTypeID=1Tue, 26 Jun 2018 10:47:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c00f8831-36b0-426d-9912-8507b31db97cpurgoufr<p>Yes I am using NRF51832 and you are absolutely right. Finally I obtained maksimum current consumption about 6.2mA.&nbsp;What I am wondering is, is this the lowest amount of consumption I can reach?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/137510?ContentTypeID=1Mon, 25 Jun 2018 15:39:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9a3742d3-7786-41a8-a2b3-564c19fb9483Stian R&#248;ed Hafskjold<p>Hi, which chip are you using? If you are using nRF52832, 13mA seems reasonable for radio RX without DCDC enabled. If you enable DCDC you can get it down to about 6.5mA.</p><div style="clear:both;"></div>
