Gazell increase maximum number of devices

[Joris]

The documentation mentions:

"Supports a star network topology with one Host and up to 8 Devices."

What is the fundamental limit behind this? Would it be possible to increase this for a network base on nRF devices, to say 32?

Hi,

There is a limitation in hardware that it supports 8 individual radio addresses. If you need to support more than 8 devices you will need to add some identification (header) in the payload itself, such that if multiple devices receive the same packet, it can check the packet if it's the intended receiver and discard the packet if not.

Best regards,
Kenneth

Hi Kenneth,

Thanks for your reply. Is this a limitation to the nRF24Lxx hardware or does this also apply to nRF5x? A colleague of yours recommended to look at Enhanced ShockBurst (ESB) instead since full source code is provided there.

Best,

Joris

I believe on nRF24-series it is 6 pipes, while on nRF5-series it is 8 pipes hardware limitation.
