Will you be giving ideas for project to do with actual hardware or could you recommend courses that do such? For example, perhaps a simple temperature sensor that relays it’s information to a cell phone or computer via BLE? You could even give a list of parts to buy at DigiKey or similar. Thank you.

Hardware ideas

Hi,
You can have a look at examples in the RIOT code base which show how to implement a BLE capable application. This example shows how to implement an heart rate sensor (based on simulated data) and retrieve the data on a smart phone.
You can adapt this example for exchanging environmental data (temperature, relative humidity) using the right BLE profile.
Interesting BLE boards are based on Nordic nRF52 or nRF52840 microcontrollers:
See for example the Adafruit-Clue which runs on nrf52840 and provide several sensors (apds9960, bmp280, lis3mdl, sht31). Support in RIOT was added recently, see here and here.
It is not possible to give an exhaustive list of parts because there are a lot all over the place.
