How to connect from one Bluetooth to other Bluetooth devices

[chandanaraju]

Hi,

I am using nrf51 dk  with sdk 12.3 and softdevice S130 bluetooth module using Keil IDE.In our project we need to send sensor data from the nrf51 bluetooth module to another bluetooth module which is Tivas's bluetooth module which is in dk board.so here my question is how do i need to connect with this bluetooth module by using bluetooth  address.Bcoz Tivas bluetooth will connect through bluetooth address with different module.

so plz how do i connect through bluetooth address and tell me  which example program do i need to use for this.

Hello,

Is your other bluetooth device a Bluetooth Low Energy (BLE) device? Or classic bluetooth device?

Are you able to program the other device as well? Or does it run on a fixed application?

Are you familiar with the terms Central and Peripheral in BLE? Which one is your other device?

Do you know if the other device connects to other devices only based on an address filter? Do you know if it uses bonding or pairing?

yes, the  bluetooth is Bluetooth Low Energy (BLE) device. we are using CC2564MODA Bluetooth low energy device. I can able to program this device.Here in this bluetooth device we are connecting to other device based on Bluetooth address means we are writing the bluetooth address in program in order to connect with device.Here based on the bluetooth address we can connect to any other different application device.when we are connecting to tablet we are using pairing and when we are connecting to other controller bluetooth board we are connecting through the bluetooth address.

It would be helpful to give a link.

That sounds like a TI device ?

You didn't answer Edvin's question - is this device running as a Central?

If so, then your device will have to be a Peripheral

Again, do you understand the roles of Central and Peripheral in BLE ?

If not, then you need to do some reading-up on the basics of BLE

There are plenty of introductory materials on the interwebs; eg,

https://embedded.fm/blog/ble-roles

https://learn.adafruit.com/introduction-to-bluetooth-low-energy

For Nordic specifically:

https://www.nordicsemi.com/Get-Started

https://devzone.nordicsemi.com/nordic/short-range-guides/b/getting-started/posts/introduction-to-bluetooth-low-energy-and-ble-devel

No doubt TI (or whoever) also have similar resources for their products...

EDIT

For getting started, it's probably easiest to stick to products from one source - rather than also having to get to grips with two different product lines, tool chains, documentation structures, etc, etc, ...

Thanks for replying.

I have attached below the link of cc2564 moda datasheet.Yes that is TI 's bluetooth  but controller we are using is Tiva's controller.Yes tiva controller is acting as a central(master) which also it should connect to tablet(slave) and one more slave device(nrf51 ). so now i need to know how to connect from nrf51 to tiva controller.
