Not able to connect the Bluetooth to other device

[Namitha]

Hi,

I  am using NRF51422  dk board in our project.We are using SDK 12.3 version , soft device S130 and keil u vision. Here the problem is I am not able to connect the bluetooth with other controller (Tiva's controller) Bluetooth. i am using the example program ble_central/ ble_multilink central example program.So here the nrf51422 board is used as central and ti's board is used as peripheral  where i am advertising the Bluetooth name. But the nrf51422 board which is scanning not able to connect the bluetooth through device name .can you plz tell me how to connect to ti's board bluetooth device. Or is there is any way to connect with the ti's board  bluetooth.plz help me to resolve the issue.

Note that nRF51 is rather old, and not recommended for new BLE designs:

Are you sure that the TI device is not requiring any "newer" BLE features that the nRF51 doesn not support?

How have you verified that the TI board is actually working, and does actually accept connections?

eg, can you see it, and connect to it using nRF Connect ?

How have you verified that your nRF51 code is working?

eg, can it connect to a standard Nordic example?

Can it see the TI device advertising?

So what, exactly, are you doing?

What debugging have you done?

Are you getting any errors returned - on the nRF51 and/or the Tiva?

Others have had success:

Thanks for the reply.Yes i have checked the Ti's board Bluetooth is working, tried to connect through Blueterm app ,which is connecting and transmitting the data.

With the example program of ble_peripheral/ ble_app_uart  it is working means the data is transmitting and sending through  nrfconnect app.

verified that your nRF51 code is working- No, i didn't check.I am trying this example program ble_central/experimental/ble_app_blinky  which is central and which is scanning for peripheral device name "Nordic_blinky"

in the example program so,i have changed the device name to "Tibluetooth" so it has to scan for this device name and should connect. But it is only scanning means the led1 is on (meant for scanning in the example program).Where the device name is advertising as "Tibluetooth' 

Trying to pair the bluetooth through device name and i am not getting any errors .plz tell me how to do

Are you sure that the TI device is BLE - not "Classic" Bluetooth?

Can't you find another Central example which will just report *all* the advertisements it finds?

[Namitha]

Thanks fpr the reply.In data sheet  they have mentioned it will support both classic and low energy .

I will try with another central example. can you tell me how to take the report of all the advertising device

The Nordic devices are BLE only - so you need to ensure that your TI device is doing BLE.
