Yes, that should do, the nRF52832/833 are both able to act as central and peripheral.

Just to clarify means that I can either use nRF52832 or nRF52833 for my Bluetooth chip and I only need to install 1 Bluetooth chip into each watch which will act as both beacon and receiver right? Sorry for asking the same question again.

I see. I don't think this will be feasible with the limited memory on the nRF52811, so the nRF52832 or nRF52833 will likely be the SoC to go for in such an application. As for the application itself, you should be aware that COVID tracing using BLE is not entirely straight-forward as there are some privacy concerns to have in mind, etc. This article, and multiple others like it are easily available online.

My receiver function is used for detecting other BLE watches for instance (Lee's watch) so that my receiver can record Lee's information to my watch and at the same time (Lee's watch) will do the same thing. So that both of them know that there had been in contact with each other if either one of them had covid.

As awneil says, please specify what you mean to do with this receiver function. Using an nRF52810 as both receiver and beacon (in the same application code) will likely not be possible due to the limited RAM and Flash memory in the nRF52810. The nRF52810 is best suited for simple peripheral application.

Please check out the nRF52832 SoC, as I think that would be better suited to the application you are describing.

Best regards,

Simon

can this chip have both functions like BLE Tag and BLE Reader? or every bluetooth chip have both of these functions.

What do you mean by that?

It can certainly act as a BLE Peripheral.

It is a cut-down chip for low-cost, simple applications - so not ideal as a Central (although, I think, it can now be done).
