This is due to the nRF51-series devices only having 1 timer instance that could do &gt; 16 bit width.</p> <p>However, when running on nRF52-devices, this restriction should not be a restriction, as it can do up to 32 bit on all timer instances. Thank you for reporting this to us, I&#39;ll report this internally.</p> <p>&nbsp;</p> <p>Kind regards,</p> <p>Håkon</p><div style="clear:both;"></div>
