Assistance Needed with ESP32 License Activation

#1

Dear Group or Support Team,

I am writing to request your assistance after experiencing difficulties with the licensing process for my Heltec ESP32 V2 device.

For several weeks, I have been developing code for a sensor that reads weather station data and transmits it to The Things Network. However, I’ve encountered an obstacle with the device’s licensing requirements that has prevented me from making further progress.

When attempting to run my code, the following message appears in the Serial Monitor:

Please provide a correct license! For more information:
http://www.heltec.cn/search/
ESP32ChipID=3CF6641C5210

After some research, I managed to extract additional information using an Arduino application:

This chip has 2 cores
ESP32ChipID=3CF6641C5210
ESP32 Chip model = ESP32-D0WDQ6 Rev 100

I attempted to use this information on the provided website, but was unable to proceed or generate a license.

Could you please provide clear instructions on:

  1. How to obtain the correct license for my device
  2. The exact procedure to activate the license
  3. Any documentation that explains this licensing requirement

I am using the latest version of Arduino IDE on a Mac computer for this project.
I would greatly appreciate your prompt assistance with this matter as it is currently blocking my development progress.

Thank you for your help.

Best regards

Forum search will reveal much of the information you are hoping for. But it’s not that complicated as you’ll see many threads with such requests on. Paging @Ashley who should be able to help.

#3

Thank you! Seems that I will have to contact @Ashley :slight_smile:

#4

Still here trying to find a solution for this Lizenz problem! Another on is: How can I write a User personally here in the chat area? Or is there anyone else who can activate a Lizenz?

#5

Same problem, I need to get my licence as well. Need to wait I think

You posted a request at 10:43pm on Friday evening. What office hours are you expecting?

#7

True! But first you have to know how this works. I absolutely didn´t understand this part, that there is a need for activating a license! Now it works! :slight_smile:

And the why I still don´t understand…

#8

Erm, you post on a forum, it’s almost certainly going to be read by a human - just like all the other requests that you will have found! So, office hours. And for any other queries on here, it’s down to when a volunteer gets around to feeling like answering.

It mean the library can only be used with Heltec ASR based chips - maybe that’s the licensing deal with ASR Micro? Who knows. But that’s the procedure and now you know, if you buy more boards, you’ll know to request the license well in advance of shipping. :wink:

Hello, I have added a license for you.

0xFA88127F 0x8690EC7E 0x25141F04 0x55109808

Hey! Thank you for reading this and the license. :slight_smile: Ciao

#11

SoI have the License. And this still doesn’t work! I still get the message to activate my license. I have an Arduino code with some functions, where I add and send the license. Here are my examples from the Arduino code:
uint32_t license[4] = { 0xFA88127F, 0x8690EC7E, 0x25141F04, 0x55109808 };
void setup() {
…
// MCU initialisieren
Mcu.begin(HELTEC_BOARD, SLOW_CLK_TPYE)
// License setzen
Mcu.setlicense(license, HELTEC_BOARD);

What else do I have to activate? What I am missing? I really appreciate any help with this!! Thanks

Enter AT+CDKEY=License on the Arduino serial port, please note that license only requires numbers and does not require spaces or 0X

@ashley this is new info… AT commands on the ESP32 series? Where is the documentation for this? :open_mouth:

#14

Almost all Arduino’s can do AT commands with the right firmware. I guess the question is which firmware!

#15

The document has been revised.
