What would be a good reason to use NRF8001 with a separate microcontroller instead of having a one-chip solution with NRF52https://devzone.nordicsemi.com/f/nordic-q-a/32999/what-would-be-a-good-reason-to-use-nrf8001-with-a-separate-microcontroller-instead-of-having-a-one-chip-solution-with-nrf52I know that few companies choose to use NRF528001 with a separate microcontroller like Fitbit. I would like to know why would they do so instead of using an NRF52 chip that already has the BLE capability and consumes less space.

You should consider the nRF8001 only when the nRF5 series does not fit your needs and you need a connectivity solution with a 2 chip solution. Even at that stage you should still consider the nRF5 series as a connectivty option vs the nRF8001 as a connectivity option before a decision.</p> <p>One of the advantages of the nRF8001 as a connectivity option is has a smaller and easier to use interface as compare to the nRF5x connectivity option.</p> <p>However you can choose to have your own custom connectivity command set for your application running on the nR5x connectivity and compare that to your needs.</p> <p>In any case use an evaluation to see what fits your needs.</p><div style="clear:both;"></div>RE: What would be a good reason to use NRF8001 with a separate microcontroller instead of having a one-chip solution with NRF52https://devzone.nordicsemi.com/thread/126606?ContentTypeID=1Tue, 03 Apr 2018 08:39:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fe5e7049-39e6-48ec-bab8-f6341cc59d97haakonsh<p>Hey John,</p> <p>I do not know of any advantage of using the nRF8001. I believe some manufacturers have used 8001 in their product because the nRF52832 was not ready at the time of development. I strongly urge you to use an nRF52 series SoC over the nRF8001 Tranceiver + ext MCU. We have a lot more resources dedicated to supporting the new 52 series than the old 8001.&nbsp;</p> <p>Cheers,</p> <p>Håkon.</p><div style="clear:both;"></div>
