You make it much more likely to get answers by posting such completely unrelated questions separately, instead of continuing on a thread like this.

Also, you should make sure to search before posting. Take a look at for example this: https://devzone.nordicsemi.com/index.php/cheap-programmers-for-nrf51822-breakout-boards

I'd also be happy if you could accept an answer here, to clear up the question.

Somebody can help to answer the question below?

Does "Segger J-Link Lite programmer" in nRF51822-DK can be used to program the SoftDevice to nRf51822 chip? Or should buy something else? :(

Thanks, Lester

Sorry for the typo. "Segger J-Link Lite programmer" in nRF51822-DK can be used to program the SoftDevice to nRf51822 chip?

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

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

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

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.

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.
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.
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.
All our devices, nRF51822, nRF8001 and nRF8002, are single mode ble devices. So they only support the Low Energy part of the Bluetooth spec.
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.

Hi there

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.

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).

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.

Hi Asbjorn,

Could you help to answer the questions above? Thanks a lot.

Could we programmed the SoftDevices to nRF51822, if we only buy the nRF51822 EK or DK that doesn't include nRF51 series SoCs?

One more question, does all of ble chip that include nRF8001, nRF8002 and nRF51822 are the single-mode ble devices?

Hi Asbjorn,

The device named nRF51822 will be able to be both peripheral and central depending on which Softdevice is loaded into the chip. So the nRF51822 EK or DK would be the way to go.
