I´m designing a bluetooth IoT BLE device and have heard that making use of the Bluetooth logo in the device implies an annual fee for Bluetooth SIG. I would like to know if this only applies to the bluetooth logo and not to the technology itself.
The device will be free and inistalled by our company so it doesn´t have to have any marketing/commercial attraction for the final user.
This is, if I design a bluetooth device but don´t print the bluetooth logo in the case nor use the word bluetooth, should I have to pay for it?
Would developing an Android application making use of bluetooth require any payment or extra cost for using this technology?
Are there any additional costs on Bluetooth Low Energy qualification/certification appart from CE/FCC marking required? I´ve checked this and this questions and it isn´t clear to me yet.
As post in the first question, if we don´t need any marketing/commercial strategy, we could go ahead with the bluetooth low energy certification related to the regulatory marking laws depending on the territory, in our case CE marking, nothing else. Is this correct?
