How do I get a key?

I bought my drone equipped with Herelink from
The owner told me to contact the manufacturer and to send them a picture of the serial number.
However, I understand that communication with the manufacturer goes through this forum…
Can I send the serial number via private message to one of the admins here?

Send a picture of the sticker at the back of the controller to the reseller.
The reseller will provide a key

after the firmware update, I need a product key. My german reseller, where I’ve bought my Herelink, is insolvent. Where I can now get this key?

Best regards

who was the reseller?

Unirobotix UG (Synosystems)

Hello friend, I bought a dront and they sold me your control system, he told me that the key is the label, but the number of digits is not considered, I write to my provider and he does not respond, can you support me?
