Nordic Thingy:52 multiple device communication

[Leonardo]

Hi, I need to get at least 3 sensors data (Accelerometer and Gyro) simultaneously and I am thinking to use the Nordic Thingy:52 for that. Our application sends these information to PC in about 15Hz.

1. Is it possible?
2. Which kind of dongle do I need to receive these information on PC?
3. Is every Thingy:52 with Bluetooth 5? At DigiKey they put as BT 4.X: www.digikey.com/.../7175577
4. Is there any example using this kind of configuration?

Hi Leonardo,

1. It is no problem sending data from 3 sensors at 15Hz.
2. Which OS are you using? Does your computer already support Bluetooth?
3. Every Thingy:52 is Bluetooth 5 Ready. This means that the chip (nRF52832) supports all the features of Bluetooth 5 except Long Range. Note that the Thingy:52 firmware does not use any Bluetooth 5 functionality.
4. Do you mean on the firmware side or the PC/Mobile side? We have example applications for Android, iOS and Web which demonstrate how to receive data from several sensors at different intervals.

Thank you, Ketil, I will sell my product using this sensor, so I don't know exactly what computer will be used by my client. I need to send together some bluetooth dongle to be sure they will use it correctly. Coukld I buy any Bluetooth 4 dongle for it?

Our software is made in Java, and at this moment it is running only in Windows.

We don't need Long Range feature.

Yes, any Bluetooth 4 dongle should work in communicating with Thingy:52. However, you might run into issues with the drivers of the OS. It will depend on which drivers you bundle with your application. Take a look at the node-bluetooth-hci-socket GitHub repo for a list of supported dongles for that particular project. Also, the latest version of Windows 10 has greatly increased support for BLE and should work without separate drivers.
