LoRa Kit 151 IDE

Hello,

I’m wondering about buying the STM32 LoRaKit 151 but there are a few questions:
The first one is what IDE was used to create examples that are provided in webpage codes? KEIL, IAR, or something else?

And secondly why the download link for “LoRa Kit 151 Pingpang test example code” doesn’t work?

Sorry, kit 151 has been discontinued.
