Reading the value of multiple hearetrate sensors via BLE

[haraz]

Dear supplier

I want to read 10 heart rate sensors that are connected to 10 person's bodies and then display them on TV. How can I do it?

Can I use nRF52832 chip? Can nrRF52832 be connected to 10 nRF52832s for data receiving? How about using nRF52840 dongle that is connected to smart TV and communicate with other 10 nRF52832s?

best regards

See the SoftDevice specifications - they support up to 20 simultaneous connections.

For developing the nRF code, an nRF52832-DK or nRF52840-DK development kit would be a far better choice than a dongle.

As the name suggests, the development kit  is intended for developing on - the dongle isn't.

connected to smart TV and

that would require you to have supporting code on the "smart TV" ...

[haraz]

Thanks alot.

It is mesh or no?

[awneil]

No - Unless the particular "heart rate sensors" in question state that they are Mesh devices.

Thanks awneil
Can I use the smart phone with Bluetooth 4 for monitoring?

[awneil]

That would depend on the capabilities of the particular phone in question but, in general, Yes!

You would also need a suitable app...
