Peer to Peer communication in nRF51422

[Ankit]

Hi,

I want to establish a peer-to-peer communication network between 2 nRF51422, such that both the nRF51422 can Transmit as well as Receive data. Is it possible to achieve so?

If yes, can I extend this peer-to-peer network to 8 or more devices? If no, is there any alternate way to achieve so?

A peer-to-peer communication network between two nRF51422 is possible.

Use the S110 SoftDevice(peripheral) on one device, and the S120 SoftDevice(central) on the other.

You can find examples for the S110 SoftDevice in \examples\ble_peripheral, for example ble_app_hrs.

You can find examples for S120 SoftDevice in \examples\ble_central, for example ble_app_hrs_c.

ble_app_hrs and ble_app_hrs_c can communicate with each other.

If you want to extend the number of devices, I think you should look into our bluetooth low nergy based rebroadcasting mesh implementation, found here.

Yes. I saw that rbc_mesh implementation a while ago. So, I just want to clarify before starting working on that implementation, that there is NO other way to achieve peer-to-peer communication for 8 or more devices? I also commented on your answer related to similar post on ANT here. Please clarify that one too. Thanks for your guidance.

There could be other ways, but with Bluetooth Low Energy this is what we can offer. You may also want to check out Wirepas Pino. I edited my answer in the ANT question, please let me know if anything is unclear.

Thanks for your answer. I have read your Edited answer on the ANT question and made some comments. Please have a look at that question again. Thanks again.
