It should not be a problem using our devices with a master from another company. The Bluetooth Low Energy protocol allow all devices to communicate with each other. As long as you designed both devices yourself, you know how your data is transmitted. This makes it easy to configure the devices to talk to each other.

OK, we actually have master from silicon labs BLE 113 and we want slave from your company. So it is possible to communicate or it is best that we have master and slave from nordic semiconductor?

As long as the master and slave adhere to the BLE standard they should communicate

In short can master and slave of two different companies can communicate? let's say I have beacon of Nordic semiconductor and Master of some xyz company ?

Is it possible to communicate them?

If you are using Bluetooth Low Energy, you can use our nRF51/nRF52 devices to communicate with any devices following the BLE specifications. You can use the same development kit for both beacon (broadcaster), peripheral, central, or observer device. Our BLE stack (S132 softdevice) support all these roles, and one device can act as peripheral and central at the same time if desired.

One more that I want to ask nordic semiconductor development kit can or can not communicate with other devices such as development kit from some other companies? For example, if there is beacon of nordic semiconductor on one side and other development kit on other side or vice versa?

Is there two different development kits one for beacon and one for master ??

A great starting point for getting started with the nRF52 DK is the Getting started tutorial here on DevZone. There is also other tutorials available, especically the BLE tutorials are helpful if you will be using the BLE feature of the chip. Notice that the tutorials are under rework, as they are written for an earlier SDK version. Our SDK contain examples for all peripherals and a lot of usecases, both using BLE and other protocols. If you want to scan for devices (beacons) and transmitt the advertising data to a computers terminal, I would recommend to start with the Nordic UART Service Client example. You have to do some small changes to the example to transfer the advertising data over UART, but the rest is setup allready.

Basically, can you send me or give me some links so that I can start learning to how to code on your development kit.

Another thing is we want some ready made example or code of Beacon side which will transmit the location information that we will enter in to it and then the other side which is the master side, in our case the development kit will receives the data and transmit it to its UART port.

First for the proof of concept I want to send AT commands from the DK to terminal software (putty).

Do you have such ready made example in your blog?

Yes, the nRF51822 have a BLE sensitivity of -93dBm, while nRF52832 have a sensitivity of -96dBm. This corresponds to a theoretical range increase for the nRF52832 of ~40% under optimal conditions.

Is there any difference in the range of communication between nRF52832 and nRF51822 other than the power consumption?

Hi,

The best alternative if you want a production ready development kit, that support Bluetooth Low Energy is the nRF52 DK, which contain the nRF52832 IC. The range of this device is up to 100m outdoor in line of sight, with typical indoor range of 10-20m.

If you need longer range, the nRF52840 PDK can be an alternative. This support Bluetooth 5.0 with the new long range feature, which can increase the range by using lower data rate. Notice that the devices you are connecting to must support this mode as well for this to work. The nRF52840 is currently only available in engineering samples and preview models, the production variant will become available in Q4 2017.

Best regards,

Jørgen
