I can get 25 meters on LOS (I think it can go far way but 25 meters is the maximum distance I can test at home) but as soon as a humanen-USTelligent Community 13Tue, 21 Jul 2015 07:38:45 GMThttps://devzone.nordicsemi.com/thread/25152?ContentTypeID=1Tue, 21 Jul 2015 07:38:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9275479f-c690-40ec-89dc-0a10e2b0bc54Susheel Nuguru<p>Jose please update/accept this thread with newer info.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/25151?ContentTypeID=1Thu, 21 May 2015 09:06:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ffeef6cd-20e9-40fd-b9b9-1dc9032f497cSusheel Nuguru<p>when do you get CRC errors?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/25150?ContentTypeID=1Tue, 19 May 2015 12:14:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:aa2788d4-db04-4db3-9c63-6a34b4932838Jose Xavier<p>BTW I got some CRC errors, this is why I first post this question.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/25149?ContentTypeID=1Tue, 19 May 2015 11:58:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c10911f6-66b7-43b6-acf3-ef77bcf54f64Jose Xavier<p>If I do some retries what should be the time interval between retries?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/25148?ContentTypeID=1Tue, 19 May 2015 11:49:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:db7ee36a-a3af-444b-b5cd-5ec41ef8f8b6Susheel Nuguru<p>It would help little bit but the basic characteristic of the signal would not change. The human body will absorb most of the signal and if the walls and floor are not good reflectors then you would not see a big difference.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/25147?ContentTypeID=1Tue, 19 May 2015 11:45:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e2730071-1954-4c30-bc72-373d6b905fe9Jose Xavier<p>could an antenna like the one in PCA10005 board help?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/25146?ContentTypeID=1Tue, 19 May 2015 11:43:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ebd05221-108b-4019-956f-c5c1e66dccaaSusheel Nuguru<p>The body will absorb pretty much everything, and there&#39;s nothing you can do with that. The attenuation is huge. It will only work if the signal can reflect off something, wall or floor.</p><div style="clear:both;"></div>
