https://devzone.nordicsemi.com/f/nordic-q-a/32528/determination-of-energy-consumption-and-maximum-range-of-ble-5Hello Guys, I have some measurements for the determination of the maximum range and the energy consumption. The experiment is based on the ATT_MTU throughput example, nRF5_SDK_14.2.0_17b948a and s140_nrf52840_6.0.0-6.alpha_API. For the experiment Ien-USTelligent Community 13Wed, 21 Mar 2018 07:43:18 GMThttps://devzone.nordicsemi.com/thread/125273?ContentTypeID=1Wed, 21 Mar 2018 07:43:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e1c58b6d-c866-4667-ae00-33f4008f66b6run_ar<p>1. You are using an old Softdevice, this was made for engineering revision A. To test Long range properly you should use the latest SD (available on request) and the latest revision of the chip.</p> <p>2. Same as 1. In addition coded phy spends a considerable longer time on air. Note that 7.5 ms intervals might not be the fastest setting. i.e. try 50ms when using long packets.</p> <p>3. Assuming it is the time used to transmit a given amount of data.</p> <p>4. yes, that is it. coded phy is basically 1 mbit that uses 8 bits to represent 1 bit. so if 1mbit is 1µs per bit, coded phy is 8µs per bit. because of this the chip will also spend more time in rx/tx, which means you could get a better range / power consumption ratio if you use 1 mbit with pa compared to Long range without PA (of course what to use depends on your application. Long range is best for sending smaller amounts of data, as the throughput is quite low compared to 1 mbit/2mbit).</p> <p>&nbsp;</p><div style="clear:both;"></div>
