Also just to clear up any confusion, I am powering the C1001 using a different power supply and it is receiving the proper current and is operating at 5V. My question mainly lies with the Rx/Tx pins.

Thank you for the response. I have a couple more clarifying questions if you can answer them. I am coding on VsCode using Platformio, which has an Arduino framework. The MCU I am using, the Swan by Blues, has Rx/Tx pins that are 3.3V tolerant. Since you mentioned uart TTL, is that potentially a reason that the code is not working from the github?
