This example sends a valid LoRaWAN packet with payload "Hello,
world!", using frequency and encryption settings matching those of
the The Things Network.
This uses OTAA (Over-the-air activation), where where a DevEUI and
application key is configured, which are used in an over-the-air
activation procedure where a DevAddr and session keys are
assigned/generated for use with all further communication.
Note: LoRaWAN per sub-band duty-cycle limitation is enforced (1% in
g1, 0.1% in g2), but not the TTN fair usage policy (which is probably
violated by this sketch when left running for longer)!
To use this sketch, first register your application and device with
the things network, to set or generate an AppEUI, DevEUI and AppKey.
Multiple devices can use the same AppEUI, but each device has its own
DevEUI and AppKey.
Do not forget to define the radio type correctly in
arduino-lmic/project_config/lmic_project_config.h or from your BOARDS.txt.

This Sketch compiles and uploads OK to an Elecrow LoraNode board but the Serial Monitor result is as shown in attached screenshot. The Elecrow board has an RFM95 mounted on an Arduino board with Pro/Pro Mini bootloader. Paul's tutorial, which I followed is here:
https://www.disk91.com/2019/technology/lora/first-steps-with-lora-radio-node-arduino/
Obviously still doing something wrong.
