BLE TO BLE

[Yash Shah]

Hello,

we want to communicate the BLE to BLE without connection how to communicate?

One BLE is continious on scaning mode and another one is advertising mode on event 

so any example code aviliable for this ?

Hi

I think the easiest here would be to use the Bluetooth Scan & Advertise sample application in Zephyr. This application demonstrates a combined BLE broadcaster & observer role. If you flash it onto two devices both should be able to scan the others advertisements for example. You can also use a beacon on one end and turn of the advertiser to only have a scanner.

Best regards,

Hello,

Thank you for reply but can you provide Nordic nrf52 example code because I am beginner in nordic

Hi

If you are new to the Nordic development scene I would recommend you get started with the nRF Connect SDK instead of the nRF5 SDK, as new features will only be added to the nRF Connect SDK as per this informational notice.

You can follow our getting started guide for the nRFConnect SDK here, and the Scan and Advertise application I linked to will have example code in the nRFConnect SDK once it's installed.

Best regards,

Simon

Hello,

As per my understanding one BLE is set in broadcasting mode and another one is observer(Central) mode.

So What exactly I can broadcast ? (I have 19 byte Frame ) and How to recieve data on another BLE connection less (scan mode ) But what exactly scan method in observer mode. Please suggest me.

Like this advertise the data

manu_fact_data[0] = 0x01; //Length
manu_fact_data[1] = 0xFF; //AD Type
manu_fact_data[2] = 0x61; //Company Identifier
manu_fact_data[3] = 0x35;
manu_fact_data[4] = 0xAA; // Product ID
manu_fact_data[5] =
manu_fact_data[6] =
manu_fact_data[7] =
manu_fact_data[8] =
manu_fact_data[9] =
manu_fact_data[10] =
manu_fact_data[11] =
manu_fact_data[12] =
manu_fact_data[13] =
manu_fact_data[14] =
manu_fact_data[15] =
manu_fact_data[16] =
manu_fact_data[17] = 0x00;
manu_fact_data[18] = 0x00;
manu_fact_data[19] = 0x00;

advertising_init();

Hi

Please check out our BLE advertising tutorial for information on what the BLE advertisement data can include (note that this one was made for the nRF5 SDK, but the advertising concepts are still the same). This is mainly device name, UUIDs, service data, and perhaps some custom data. 

What exactly do you want do advertise, and are you having issues picking it up on the scanning (central) side?

Best regards,

Simon
