This is mostly due to size limitations, as advertising extensions takes a lot of memory to implement, which is why our smallest SoCs does not support it. I would suggest going for the nRF52820 or nRF52832 instead if extended advertiisng support is a requirement.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
