Hi,

The ble_app_uart example would be a good starting point for this. But you need to reconfigure the advertising parameters so that it advertises in non-connectable mode before you restart advertising (if you want it to advertise as a beacon).

[quote user="manoj.hiwarkar"]And in beacon is it possible to change the major and minor values over the air.?[/quote]

No, the beacon example advertises in non-connectable mode. Steps you should implement:

Advertise in connectable mode
Provide a service that let's you write data to a characteristic.
Reconfigure the advertising parameters and restart advertising with the data that was written to the characteristic.

See actually I have to receive the data via bluetooth once and start advertising it continuously. Will it work like this? Shall I try this with beacon code or uart code? And in beacon is it possible to change the major and minor values over the air.?

Hi,

It should be defined at the top of the file. I'm using SDK 16.0 and it looks like this:

I am not able to find APP_ADV_DURATION and there are lot of ble_evt_handler. Where exactly?. I am using SDK 13 by the way.

Hi,

If you want to advertise continuously in the ble_app uart example then you can set APP_ADV_DURATION to 0. The peripheral will then advertise continuously until a central connects to it. If you wish to continue advertising after a connection then you would have to call advertising_start() in the BLE_GAP_EVT_CONNECTED event in the ble_evt_handler.

Note: You would have to increase the link count in the sdk_config.h file if you wish to connect to more centrals simultaneously.
