Does this library really support US915?

[MichaelBla]

I can't get this to connect in the US although I can see it try in my gateway.

I can't find anyone else having success with this in the US so I wonder if it has been tested here.

It does work in US915. Besides, your gateway sees it, ensure the keys are set exactly the same on both ends and both are configured for the same joining method (OTA or ABP).
For joining, use US915_HYBRID, not just US915. Now the sensor will transmit on LoRa channels 1 through 8 instead of all 64 channels (your gateway likely does not support all 64 channels).
We are using a Multtitech Conduit Gateway so we also set the ADR mode to 0 and dataRate to 0.

Changed to US915_HYBRID. The activation is OTAA on both ends. LoRaWAN Version is MAC V1.0.2. Got one successful connection this morning and then repeated failures. The only successful connection used PHY V1.0.2 REV A but later tried PHY V1.0.2 REV B but that didn't help. Using US 902-928 MHz, FSB 2. Frame counter width is 32 bit. Nothing set for RX2 Data Rate Index or RX2 Frequency. Two gateways in here. I have Vitron device that seems to use the gateway without problem.

I am having success with the Helium network in North America using the new MKRWAN feature on the Portenta where you can enable channels:

For TTN I think you have to enable the "0" channel, can someone check:

  modem.disableChannel(0);
  modem.enableChannel(1);    // only one enabled for Helium

Demo program here

Here is the code I am using:

/*
  Helium Send And Receive

That worked! In that I saw my first payload, ever. I was using US915 and enabled channel 0 and disabled channel 1. I'll have to go through your code and figure out what it was trying to send and if my decoded payload of "\u0001g\u0003!" is meaningful. Sorry, I'm obviously new to this and having never received a payload before I don't have any experience handling it. I didn't wire-up any LEDs. I just assigned them to outputs 4-6. Thanks! I finally feel like I have a foot in the door. Michael
