    I just received my V4 Mini Ultra Pro. I am following the guide to set it up for the things network but am bit unsure on the soldering that needs to happen. In V3 I needed to connect DIO1 with D6, as well as RESET and D3; and then maybe DIO2 with D7. In the V4, RESET is still connected with D3, but DIO1 and DIO2 would both be connected together with D6. Is that what should be done, or is it only DIO1 with D6, leaving DIO2 unconnected?

    Hi Thomas,
    DIO2 is only needed in FSK mode. I only notice this after reading the latest LMIC library that has since been maintained by MCCI Catena. So, you only need to bridge D6 to DIO1. This also save us a pin.
