https://devzone.nordicsemi.com/f/nordic-q-a/4615/ble-advertisment-interval-minimum-sizeIn ble_gap.h I noticed a parameter called BLE_GAP_ADV_INTERVAL_MIN, which determines the minimum gap between BLE advertisements. Current setting is 0x0020. Currently in AdvertiserInitializer.h, the CONNECTABLE_ADV_INTERVAL is set to 0x0020.

That answers my question quite nicely. It also reminds me to do my homework, read the documentation!</p> <p>I am able to send data at a high rate, about 20ms to 30ms between packets. The only issue I&#39;m having is with devices receiving the data, for example Android or Linux. They seem unable to keep with the data rate. If I set up four machines to receive the data, they each receive a different subsets of the data. However that is probably more an OS, driver issue.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/16394?ContentTypeID=1Fri, 28 Nov 2014 14:24:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1c01112f-fc37-47b9-9d61-37335921adabPetter Myhre<p>The smallest possible advertising interval is 20ms, this is defined by <a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/6708.Core_5F00_v4.1.pdf">Bluetooth Core Specification 4.1</a>, Volume 3, Part C, Section 7.8.5.</p> <p>In BLE there are three advertising channels, and one advertising packet is sent on each of these in each interval.</p><div style="clear:both;"></div>
