How to configure beacon to receive data/indication from a gateway or external device ?

[Jaydev Borkar]

I have a requirement wherein I use the nordic chip to transmit the beacon data , after beaconing I want the beacon to go to a listen state and accept the data from a linux based Gateway . Is there any article which will guide me to accept the data from external device like gateway into the beacon when it is in listen mode.

Hi,

I do not fully understand what you try to achieve.

What do you mean by saying that you are done "beaconing"?

I would recommend having a look at some of our short range - ble tutorials.

This tutorial discusses advertising, and is a good place to start

Hi , 

my question is simple.  can I have bidirectional communication using nRF52 in beacon mode .

Hi,

When a device is advertising (a typical beacon advertises only) it is possible to add a scan response packet only sent when someone responds to the advertising data. It can be possible to alter the scan response packet depending on who it is that responds to the advertisement. I am not sure what you mean with beacon mode, but I wonder if you think of a device which is non-connectable and advertising only?

However it sounds like you want to create a connectable device which advertises until someone connects to it. The BLE Blinky Application example advertises indefinitely, but can be connected to at any point in time. When connected to it is possible to send commands to the device.
