Hi milav,

There is no pairing in the same way as in the regular Bluetooth low-energy.

See this page for more information.

Quote:

The Bluetooth Mesh is a broadcast-based network protocol, where every device in the network sends and receives all messages to and from all devices within radio range. There is no concept of connections in the network topology, and any device in the network may relay the messages from any other device. This property allows devices to move around and drop in and out of the network without having to compensate for the change in topology.

Hello,Sigurd..

This nodes means two Bluetooth device can transfer the data between them. is this node paired? means once this master Bluetooth save slave device name after then, it is connected automatically every time when slave is advertising.

Thank You, Sigurd...

This information help me a lot.

No, you have max 8 connections on nRF51 and max 20 connections on nRF52.

If you need such a big network(with more than 100 devices), I would recommend you to take a look at the Bluetooth Mesh, where the theoretical max number of nodes are 32768.

For more information about BLE mesh, take a look at this blog post and this infocenter page.

Thank You, Sigurd...

This 20 number is just a testing number....actually we want more than 100 concurrent connections.

one Master and many slaves..... all are handle by only one master in concurrently.

is this possible in nrf51 series chip...??

Hi milav,

The nRF51 series uses SoftDevice S130, S130 supports up to 8 concurrent connections, but only one connection as peripheral.

The nRF52 series uses SoftDevice S132, where you can have 20 connections in any combination between Peripheral and Central.

Park State was deprecated and removed in 2016. And it was, as far as I can tell, a classic bluetooth state not a BLE one so not applicable to the nRF5x series which are BLE.
