Also, what is the default number of send attempts?en-USTelligent Community 13Wed, 24 Dec 2014 07:59:34 GMThttps://devzone.nordicsemi.com/thread/11425?ContentTypeID=1Wed, 24 Dec 2014 07:59:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bf6ec693-d609-475f-ab46-0fe5692e8163Philip Freidin<p>Tim&#39;s answer above points to documentation 5.2.0. I&#39;m now looking at 7.1.0 and I can&#39;t find equivalent information. I did find the file nrf_gzll_constants.h which seems to have the same default info. Note that the comments in this file warn that editing this file will have no effect(because the library is pre-compiled). You would need to call various functions to change these defaults.</p> <p>I found this line that addresses your second question</p> <pre><code>#define NRF_GZLL_DEFAULT_MAX_TX_ATTEMPTS 0 ///&lt; Default maximum TX attempts for each packet. A value of zero implies maximum </code></pre><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/11424?ContentTypeID=1Thu, 31 Jul 2014 10:29:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4d823015-3c4c-4e91-aa38-912b8c11624cTim<p>See <a href="https://devzone.nordicsemi.com/documentation/nrf51/5.2.0/html/a00930.html#gad1a22ed83d9713817fdbe5d23b7a568a">here</a>.</p><div style="clear:both;"></div>
