When there is timer interrupt, the data will be send. What I wanted to ask is that What is the min send interval over BLE ? How quick can I send the data ? is 10msen-USTelligent Community 13Wed, 16 May 2018 10:07:38 GMThttps://devzone.nordicsemi.com/thread/132224?ContentTypeID=1Wed, 16 May 2018 10:07:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:df51a66f-52d2-4f36-b066-d7a0441368b2Turbo J<p>Your 10ms is <em>very</em> fast, depending on the &quot;other party&quot;. Android typically allows 15ms connecion interval, while iphone will allow 50ms without the HID service trick - but even that may not yield timing below 10ms.</p> <p></p> <p>Note that I recommend setting a flag in the timer handler and sending from main() instead.</p><div style="clear:both;"></div>
