Does nRF52810 support Central in SDK version 16.0.0?

Hi Everyone,

We are using nRF52810 in our project. It Supports peripheral mode. I didn't find any example code regarding central role. Does nrf52810  supports Central + peripheral soft device?

We have following requirements.
We need Central role for for scanning near by  BLE devices.
Peripheral role for NUS service.(UART over BLE).
Bootloader for uprading firmware over UART.

Hi

The nRF52810 does support being a central,  but it is not very well suited to being one due to its limited RAM and Flash memory. The S112 SoftDevice only supports peripheral/bootloader applications and is the most commonly used SoftDevice for the nRF52810. However, the nRF52810 can also be used with the S132 SoftDevice, which supports central application as well. The issue is that the S132 SoftDevice is larger in size and takes up more space in Flash than the S112 SoftDevice, and a central application (especially one implementing multiple peripherals and a bootloader) will take up more space in Flash than a simple peripheral does. 

For your requirements, I would recommend looking at the nRF52832, nRF52833, or nRF52840 which have more storage than the nRF52810/11 and is better suited for central applications that also needs a bootloader, etc.

I think all above chips doesn't have pin to pin compatibility with nRF52810 32pin. We need to change our schematic.

Thank you very much for your suggestion.

Hi

You're correct, the "central recommended" chips do not have a 32 pin footprint available, so a change of schematics will be necessary.

Hi

We will do the necessary updates in schematics. Thanks for your help.

Best regards,
