https://devzone.nordicsemi.com/f/nordic-q-a/765/differences-between-develop-using-eclipse-and-keilHello, I am going to start programming BLE application, and I would like to know which enviroment is best to program it. Are there too many differences between programming using Eclipse and Keil? Are there enough support to program with Eclipse? en-USTelligent Community 13Mon, 28 Oct 2013 18:03:32 GMThttps://devzone.nordicsemi.com/thread/3855?ContentTypeID=1Mon, 28 Oct 2013 18:03:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fac4ee53-2a28-4dc1-be09-f6904221d3d4syntroniks<p>From what I have found, the evaluation code-size-limited version of uVision 4 is more than sufficient for my needs. As long as it is installed before the Nordic SDK, I highly recommend it. I have tried the eclipse configuration and beleive it would lead to longer development times (because I am not familiar with the nuts and bolts behind it.)</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/3856?ContentTypeID=1Mon, 28 Oct 2013 15:29:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8bae4d62-af8b-4cb4-b2d6-9d53ae490926Ole Morten<p>There is no doubt that Keil is better supported from our side than GCC/Eclipse, for example since only the heart rate BLE example is available for GCC.</p> <p>However, if you&#39;re ready to fiddle a little yourself, there shouldn&#39;t be any major problems with using Eclipse and GCC for the nRF51822, and we&#39;ll try to help you as best we can if you hit problems. There have also been several questions here on Developer Zone that might be useful to refer to.</p><div style="clear:both;"></div>
