https://devzone.nordicsemi.com/f/nordic-q-a/67243/expected-range-when-using-nus-with-a-datarate-of-40kbit-s-5kbyte-sHello, In our project, we have a BMD-300 module, which contains a nRF52832 chip, and a nRF52840DK. The BMD-300 module is used as peripheral and the nRF52840DK is used as central. The BMD-300 module sends data via NUS to the nRF52840DK with a dataen-USTelligent Community 13Sun, 18 Oct 2020 10:08:44 GMThttps://devzone.nordicsemi.com/thread/275460?ContentTypeID=1Sun, 18 Oct 2020 10:08:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f303fcb4-04b5-4d0a-ab81-e1cc1c0af12fMichael01101<p>Hello,</p> <p>thank you for your response.</p> <p>I will check that out.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/275375?ContentTypeID=1Fri, 16 Oct 2020 13:09:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:161018ea-a7d6-45de-b6c9-13eb27e15614Andreas<p>Hi,</p> <p>&nbsp;</p> <p>This is highly dependent on the environment in your area, but generally ~5m does not sound a lot. It might be that the module antenna is not optimally if you have placed it incorrectly or something, you should compare with a NRF52 DK.</p> <p>Also check out this range calculator from Bluetooth SIG:&nbsp;<a href="https://www.bluetooth.com/learn-about-bluetooth/bluetooth-technology/range/#estimator">https://www.bluetooth.com/learn-about-bluetooth/bluetooth-technology/range/#estimator</a></p> <p>&nbsp;</p> <p>Best regards,</p> <p>Andreas</p><div style="clear:both;"></div>
