https://devzone.nordicsemi.com/f/nordic-q-a/114077/understanding-about-connection-supervision-timeout-parameterHello everyone! I&#39;m testing a device using nRF52832 module in quite noisy environment. I&#39;ve experienced BLE disconnect and looking at RSSI value, I can see it went down to less than -80 dBm for a few seconds. I&#39;m trying to increase the connection supervisionen-USTelligent Community 13Mon, 18 Nov 2024 18:12:04 GMThttps://devzone.nordicsemi.com/thread/510951?ContentTypeID=1Mon, 18 Nov 2024 18:12:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8c9502ae-4981-44d2-b75b-4b07bbe6798dTai<p>Sorry for the late reply!

Does that have a relation with the RSSI of the slave device?[/quote] <p>The count down start when the device does not receives a packet within the connect event period, when the central device (in your case, the iPad) stops receiving packets from the peripheral device (your nRF52832 module). This could be due to various reasons such as interference, signal strength dropping below a certain threshold, or the peripheral device going out of range.</p> </div> <div>The RSSI value you mentioned (-74 dBm) is likely the signal strength at which the central device is receiving packets from the peripheral device. However, it&#39;s important to note that RSSI values can fluctuate due to various factors such as interference, distance, and obstacles between the devices.</div> <div></div><div style="clear:both;"></div>
