Indeed, what ^^ he said, couple of tips on asking questions:
- If you are going to ask on the TTN forum funded by TTI, make sure there is something that explains how it’s related to LW on TTN/TTI
- Which pins 17 & 18? The ESP32-S3, the header pins (of which there are two lots of 17 & 18)
- Perhaps help out the volunteers with a link to the resources you looked at - helps them to help you and it indicates you did some prior research.
If you post on the forum, it will be a race to see if BNS or nmcc answers - guess who they are!
