Assistance Needed: Sending Data to The Things Network using LoRa-E5-Dev-Board and Mbed OS

Hello ARMmbed Community,

I am currently working on a project using the LoRa-E5-Dev-Board with Mbed OS, and I need assistance with sending a simple “Hello World” message to The Things Network (TTN). I have encountered issues while using the provided LoRaWAN example, and I’m not receiving any results.
