Wireless Stick Lite V3 - How to enter license?

Hi
I have accidentaly cleared the flash of a Wireless Stick Lite V3 (esp32s3 with the 0.0.7 environment) when fixing the upload firmware issues and continous rebooting.

In Wireless Stick Lite v2 I used

uint32_t license[4] = { 0x3F2169DB,0x52C884FD,0x84BA6634,0x6C77322C };
then
Mcu.init(xxxxx, license);

to load and start the Lorawan module

but in the V3, there is no way to use Mcu.init() but only Mcu.begin() to start the Lorawan module, and I get the error message:

Please provide a correct license! For more information:

How can I can correctly provide the license in the Stick lite V3 ???

Thanks
Antonio

Use this AT command. AT+CDKEY=A8593DDC3******1F023EDE6

I have the same problem, how can I enter the AT command? I use the serial ARDUINO IDE, but the STICK LITE V3 keeps sending a message on the serial monitor: “Please provide a correct license! For more information:” it does not receive the AT commands in any way. How to use AT commands?
