Yes, this goes for the nRF Connect SDK as well, the SoftDevice/Zephyr controller with central features will not have much room for a "real" application on top. I strongly recommend choosing one of the "larger" nRF52 series in terms of memory for central applications.

Best regards,

I thought more about using nRFConnect instead of nRF5 but I imagine that the answer is the same... :D

Hi Julien

The nRF52805 and nRF52810 is not good fits for Bluetooth central applications I'm afraid. They are designed for simple peripheral devices like sensors with BLE capabilities, etc. The SoftDevice and BLE stack to support central application features is simply too big to realistically fit the BLE stack (SoftDevice) and an application that's doing something useful.

Best regards,

Simon
