https://devzone.nordicsemi.com/f/nordic-q-a/33533/max-packet-length-with-s112Hi Nordic &amp; friends, As I know, DLE(data length extension) is not supported in S112. We are using nrf52810 in our development, so I make a test. A long data packet(&gt;=20 bytes) is sent by the client. And I find out that the max length is 61 bytes.en-USTelligent Community 13Thu, 26 Apr 2018 08:58:59 GMThttps://devzone.nordicsemi.com/thread/129900?ContentTypeID=1Thu, 26 Apr 2018 08:58:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:83109523-a3cf-4296-bd5c-e914648e8ab2Mttrinh<p>Hi,</p> <p>1. You should be able to receive more than 20 bytes with/without DLE.&nbsp;</p> <p>2. Not really sure why you will disconnect when you send more than 61 bytes. Can you provide me with a sniffer trace? Do you do MTU exchange before the issue happens?</p> <p>3. Sending more than 27 bytes packets might improve throughput a bit because there will be less overhead. But without DLE packets larger than 27 bytes will be fragmented so the improvement is probably not that much.</p> <p>&nbsp;</p><div style="clear:both;"></div>
