Yes. From the sample stage on, the reference-app source may be used in your own commercial app, with no license fee and no royalties. You pay only for the recorder cards.
Yes, in two ways. Build your own app on our reference source and put your brand on the recorder, or, from 500 units, give your users our published app showing your logo, name and colours, with a 10% revenue share.
The reference app is the SDK: plain Java source for scanning, connecting, device information, file list, download and delete over Bluetooth LE, with a protocol document. The order edition adds live audio, remote recording control and reconnect handling.
Samples from 1 unit at US$55. Our app under your brand from 500 units. The order-edition source code comes with a first order of 1,000 units or more.
The evaluation pack lets you check the hardware at no cost. The sample-edition source covers the basic Bluetooth functions; the order edition adds the harder parts, such as live audio and reconnect with recovery of missed audio, which we deliver with a volume order.
No. The official app's source is not provided under any option. If you want every function without development, use the official app under your brand.
With 500 units or more, your users download our app and see your brand. You receive 10% of what they pay for AI services, on the sale price net of refunds.
Yes. The protocol is the same on iOS. iOS hides the Bluetooth MAC, so the recorder returns it on request (the device ID), which lets an iPhone app tell cards apart.
