Detect Central device failure and route peripheral to alternate central device

[chetanhiremath]

Hi Team,

In BLE5,

1) Can we connect a peripheral device to multiple central device?

2) Is it possible to check if connecton fails with any central device in perpheral code?

3) Can we code peripheral device to send data to alternate central device on failure of default one?

My requirement is to connect 8  to 20 peripheral device to a central device(say HUB-1) and also I need a backup central device (say HUB-2).

- So by default all peripheral device will connect with and transfer data to HUB-1.
- If HUB-1 getting fail then all peripheral node should automatically connect and start data transfer to HUB-2.

Please help me to uderstand nordic ble5 devices and sdk features to solve this problem.

Thanks,
Chetan

Hi,

1) Yes, one peripheral can connect to multiple centrals. See the Experimental: BLE Multiperipheral Application example, which does exactly that.

2) Yes, you will know if connections fails and/or if you get disconnects, through BLE events that your application can handle.

3) Yes, that should be possible.

I recommend having a look at our general nRF5 Getting Started guide, the Getting Started part of the nRF5 SDK v15.0.0 documentation, as well as the tutorials section here on DevZone.
