PANIC: unprotected error in call to Lua API (bad argument #1 to 'mode' (number expected, got nil)) about lorawangateway

Can you run CONFIG.print() in order to check your current configuration?

The mode function is used for pin modes. If one of the pin settings is missing in your configuration this may cause the unprotected call...

The values in config.lua are only used if config.json does not exist. Maybe your config.json is not correct. Can you remove it?

It´s always a good idea to erase all memory of the ESP board before upload a new firmware. Not doing this, could result in some strange errors like this one.

Thanks for coming back to my problem. I have erased the flash. Uploaded the firmware again and the four src files. A config.json does not exist.

What ESP8266 hardware are you using and how much flash memory does it have onboard? I am using WeMos D1 Mini's which have 4Mb flash memory.

The ESP8266Flasher.exe in this repository is configured for ESP8266's with 4Mb flash memory. It flashes two files: the lua firmware and some espressif provided configuration file (esp_init_data_default.bin). The latter has to be flashed on the correct address depending on the flash memory size...

If you have a different flash size look on this page for the correct address. The address can be configured on the config tab of ESP8266Flasher.

Jaap, thanks for coming back and pointing in the right direction. I have to blame myself :(. Main problem forget to upload the "esp_init_data_default.bin" and using the wrong lua loader.
Solution: first erase flash, uploading the two bin files, according to config\config.xml
BTW ESP-12E is also 4MB, according to the reference page, a WeMos D1 Mini is also 4MB and not 4Mb, So the config is unmodified appliccable.
Switched from Windows Lualoader 0.91 to nodemcu-uploader on Linux, uploading the files about 100 times faster and without complaining :).
Now its operational and OTAA works!
Thanks for your tremendous effort!
