nRF52811 / S140 - Support for multi-role

[Squonk42]

Hi,

Is nRF52811 / S140 capable of simultaneously being in peripheral (connected slave) and central (connected master) mode like described in this blog post https://jimmywongiot.com/2021/05/27/ble-multiple-central-peripheral-role/?

I am only interested in a simultaneous single peripheral / single central configuration.

Best regards,

Michel

Hi Michel

The nRF52811 has very limited RAM and Flash memory and is not very well suited to being a central in the first place. The nRF52811 can barely fit the simplest central applications onto it, so both a peripheral and a central application won't be possible I'm afraid. The nRF52832/820 are the smallest (in terms of memory) SoCs that will be able to run multi-role applications.

Best regards,

Hi Simon,

It looks like the nRF52820 may be the most interesting chip: smaller (only 2.2% larger than nRF52811), cheaper than RF52832 and USB availability, thank you for your answer!
