How is this module programmed for its applications? Is there a SDK or toolchain?

You can use the firmware from Adafruit for it (Bluefruit52): https://github.com/adafruit/Adafruit_nRF52_Arduino They base it on this firmware: https://github.com/sandeepmistry/arduino-nRF5 I use a JLink segger to program the module and after that I can reprogram it using the UART, I like the Adafruit solution since they let you program it right from the Arduino IDE and that makes life very easy. I can reprogram the name that one sees in scanning for devices though, but one can set the 'local name' and even things like peripheral information from within your Arduino sketch.

Several questions: When I receive the module, is there already a bootloader flashed? If there is a bootloader flashed, is it the Adafruit bootloader or the Nordic bootloader? Is there already a soft-device flashed? What other way to flash the virgin device? I don't want to buy the Segger Jlink. Thank you.

Hi there, Our module is only pre-programmed with Raytac’s testing code which is used at the factory for functionality testing. Bootloader is not included. You can follow reference circuit in our spec sheet to connect the module and will see BLE advertisement “MDBT42Q” on BLE search when connections are successful. To program the module, you can either use Segger J-link or any nRF5X DK you have. Both are officially recommended by Nordic. thanks.

Are both the 32KHz crystal and dc-dc inductors included in the module? OR do I need to add them while designing my circuit around this module?

Is it possible to hand solder this module? It looks like it might be a bit of a challenge...

It is possible but I use solder paste and it requires skills if you want to bake it on a normal PCB adding wires to it is doable using a normal soldering iron I guess.
