Hi,

I suggest to start with:
https://infocenter.nordicsemi.com/topic/ug_getting_started/UG/gs/product_development.html

The latest nRF5 SDK with documentation is available here:
http://developer.nordicsemi.com/nRF5_SDK/nRF5_SDK_v17.x.x/
https://infocenter.nordicsemi.com/topic/struct_sdk/struct/sdk_nrf5_latest.html

Also check out:
https://www.youtube.com/watch?v=YZouRE_Ol8g&list=PLx_tBuQ_KSqGHmzdEL2GWEOeix-S5rgTV (the screenshots in the beginning has changed a bit, but the rest of the tutorials should be useful to use the SES tool for develoment).

To answer your questions:

1. Yes, I recommend to get an nRF2-DK, since all the examples in the nRF5 SDK are setup to use that by default.

2. We do not support Arduino, so you likely will need to use nRF5 SDK libraries and drivers yes. E.g check out TWI (I2C) example here:
https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.0/examples_hw_peripheral_devices.html

3. You do this through SES as shown in the tutorials above.

4. UART is typically nice to use, the nRF52-DK will enumerate a COM port that can be used to transmit and receive data over the serial interface.

5. All source code for hardware drivers are available in nRF5 SDK.

6. Yes, most of the examples show this.

Best regards,
Kenneth

Have you looked at the Product Specification, and other documentation? That describes the capabilities of the chip

Any particular reason for choosing that one as opposed to, say, nRF52832 ?

Yes - see the Product Spec

I would strongly recommend that you do not (start) your development on the Dongle - that's not what it's intended for.

Get yourself an nRF52840 Development Kit (or kits) - as the name suggests, that is the place to do development!

The interactions with the hardware ("drivers") will be different - so will require rewriting.

If your existing "libraries" are well written for portability, then they should be easy to port

[quote userid="79831" url="~/f/nordic-q-a/63743/nrf52840-basic-questions"]Which way is the easiest to communicate with module 1 by serial input[/quote]

The Dev Kit has a built-in USB-to-Serial (UART) converter.

[quote userid="79831" url="~/f/nordic-q-a/63743/nrf52840-basic-questions"]Is a public library for NRF52840 available[/quote]

The SDK is provided as source:

https://infocenter.nordicsemi.com/topic/struct_sdk/struct/sdk_nrf5_latest.html

The BLE Stack itself - the "SoftDevice" - is binary:

Yes - see the Product Spec
