The chipset that can support Peripheral/Central role

Lester

Hi,

We would like to implement a scenario that need two BLE devices, One is Peripheral that able to broadcast and connectable, another one is Central that able to scanning and send a connect request.

According to the different roles, what chip can do the actions as above? Which development kit should we used? Please give us your comment.

Thanks, Lester

    Hi there

    1. What difference between nRF8001 and nRF8002?

    The nRF8001 is a general purpose BLE connectivity device controlled by an external microcontroller over a proprietary SPI link. The nRF8002 is single-chip Proximity device which is configurable, but not programmable.

    1. Does nRF51822 can controlled by external MCU (like arduino)? if so, they communication through UART?

    Yes, if you use the SDK's serialization library (over UART).

    1. What difference between nRF51822 DK and EK?

    The DK is designed to be used in conjunction with the nRFGo motherboard, which is sold separately. The EK is a standalone kit, no further hardware required.

    1. The difference is that nRF8001 supports all peripheral defined profiles and services since it needs to be controlled by a host microcontroller. The nRF8002 is a system on chip with defined set of profiles and services implemented. So the nRF8002 can only support those profiles and services that are specified in the product sheet.
    2. Yes, you can control the nRF51822 from an external host MCU either through UART, SPI, I2C. Currently there is code example for implementing BLE across UART commands in the nRF51 SDK on Nordic website.
    3. DK is the development kit and contains modules that is intended to be plugged into the nRFgo Motherboards. It has more buttons and LEDs available. The EK is the evaluation kit and is a smaller board that’s plugs directly to a USB cable. It’s more compact, but has access to all GPIOs, but limited amount of built in buttons and LEDs.
    4. All our devices, nRF51822, nRF8001 and nRF8002, are single mode ble devices. So they only support the Low Energy part of the Bluetooth spec.
    5. You will get access to the Softdevice and SDK with either DK or the EK. So you can buy the kit that fits your needs the best.

    Take a look at this for the differences between the kits: https://devzone.nordicsemi.com/index.php/what-s-the-difference-between-nrf51822-evaluation-and-development-kits

    Also, this site works much better if you can try to post separate questions separately, instead of collecting them all in one reply.

    Hi,

    First, thanks for all of the answers. But I also have one question.

    If I want to programmed nRF51822, use nRF51822-DK's "XXX" can be realized? Or I should buy other thing?

    Thanks, Lester

    Not sure what you mean? You want to use the DK as a programmer for a custom board?
