I have misplaced the ID of my LoRa 32 V2

I have misplaced the ID of my LoRa 32 V2 433-510 MHz modules and am having trouble working with them due to lack of license.

Could you help me get my license back?

I will thank them!!

The chip ID calc method had changed in espressif framework. Please read the chip ID via this code:

github.com

Heltec-Aaron-Lee/WiFi_Kit_series/blob/master/esp32/libraries/ESP32/examples/ChipID/GetChipID/GetChipID.ino

/* The true ESP32 chip ID is essentially its MAC address.
This sketch provides an alternate chip ID that matches 
the output of the ESP.getChipId() function on ESP8266 
(i.e. a 32-bit integer matching the last 3 bytes of 
the MAC address. This is less unique than the 
MAC address chip ID, but is helpful when you need 
an identifier that can be no more than a 32-bit integer 
(like for switch...case).

uint64_t chipId = 0;

void setup() {
	Serial.begin(115200);
}

void loop() {
//	  chipId |= ((ESP.getEfuseMac() >> (40 - i)) & 0xff) << i;
