@sineverba - 1 rule of debugging, remove as much as possible.
Can you try to use a 3.3v MCU directly with your breakout board? That way you can eliminate that the problem might be level shifting and work down the wiring to a minimum?

@sineverba it looks fine, but as we don't see what you connect this to from the pinheaders its only half of your connections. The board looks fine but it could be the other end (MCU side) that is wrong as well?

Also, in my experience you need a good antenna on both GW and nodes to even get a communication. Once the communication is up its solid but it took med some time as well to establish. I dont know if the antenna-trace might be acting as a antenna as well?

Maybe you could post pictures of your breakout attached to the MCU and also logs from GW and node.

These arrived today...
New gateway and nodes with signing is first on my list.

@ryanmt sorry I have missed this thread. I'm following now as well if I can help out with any hardware questions.

How are you powering the nodes? (Booster or lowered bod?) Can you upload a picture of the nodes and gateway? Sometimes more eyes can spot something.

You should not power the nodes both with the debugger and battery. Please de-attach the VCC from ftdi debugger. You should only have Gnd rx and TX connected while debugging. Rst can be connectws if you want.

The biggest concern is in most cases power or antenna.

This board uses MysX and connects to MysX 2.0.1 and above. MysX connector should be placed with pin 1 towards the corner of the motherboard. It means it will not align properly if you connect this to EasyPCB rev 9 and below. You need to connect this to EasyPCB Rev 10. If you are using any other Motherboard please check alignment before using.

@mr_sensor correct. As I said I'm no expert with the amplified version but that looks ok. I suggest you try it out. If it's wrong you will get an error and you can post that .

@mr_sensor i think it should be the same pin out. Gohan might now better on the amplified version. As I said I don't use those much.

What kind of error do you have now?

@dakipro what kind of setup do you end up with regarding bootloader / bod? What do you use to reprogram the pro minis bootloader?

@sineverba it is much to learn and instead of me trying to make a half ok job I would suggest you search SSR vs mechanical relay. I think greatscott did a great Youtube video about it.
