How to time-share switch between BLE and 2.4G private protocol

[lynnyang311]

Hi, We have a smart product, which has two application scenarios. One is the use of BLE peripherals, similar to sports bracelets;The other is the 2.4g private protocol mode .I have the following questions:

1. How to time-share switch between BLE mode and 2.4G private protocol mode ?  Is there any relevant technical documentation?

2.  How can I send data to the broadcast device without connecting the device while scanning the device?

Hi. 

1.
We have examples to demonstrate multiprotocol examples: 
Multiprotocol application

The Multiprotocol Application is an example that implements the Heart Rate profile in Bluetooth mode and the Gazell device mode.

2. 

Not sure if I understand the question, could you elaborate?

Br,

Thank you for your reply.The second point is how the broadcaster can get the data sent by the scanner without connecting to Bluetooth.

[Joakim Jakobsen]

I understand.

If you have a device that is only a broadcaster, it will be hard to receive any data from the scanner. The "broadcaster" device will have to swap and scan for any packets broadcasted by the "scanner". Similarly the "scanner" will have to swap and broadcast data instead of scanning.

There is only one radio on the nRF so you will have to swap between scanning and broadcasting data.

Both sides are nRF52 chips, one is the bracelet and the other is nRF52840 DONGle. 2.4g mode is added to the bracelet end. When you want to broadcast via Bluetooth, you will receive the conversion signal of nRF52840 Dongle and switch to 2.4g mode

My broadcaster can receive data. Can the scanner send special data in the scan request?
