Aodyo Sylphyo - you can lie and deceive consumer if you just want more money

    It is quite overpriced wind synth (and midi controller), with wireless capability.

    Note that company tells you

    Regarding your comment about no bluetooth functionality in the Sylphyo, we chose not to include bluetooth connectivity because it is generally slow, unreliable and has poor range. Instead, the proprietary wireless technology that connects the Sylphyo with the Link receiver has a range of more than 20 metres, a latency of less than 1ms and is very reliable.

    Problem is that here they openly lie.

    Inside we have this:

    BT832XE is a Bluetooth 5 module with nRF52832, SKY66112 power amplifier,.

    Yup, just quite standard wireless Bluetooth board with RF amplifier.

    So, this:

    Is extremely expensive bluetooth adapter inside, if you need it only to connect to computer :-)

    Otherwise it has other things, but for 99% of users it'll be just for bluetooth.

    Comment about Sylphyo using Bluetooth statement

    Hi!

    Just a quick answer and explanation to your statement about the Sylphyo using Bluetooth as there seem to be a misunderstanding here.

    As you investigate and noticed we are using a Bluetooth capable wireless module the BT832X (which is also ANT capable). The protocol for this device can be Bluetooth, ANT or proprietary. But as stated we are NOT using bluetooth protocol because of latency and range issue: we are using a proprietary protocol which is much more efficient latency-wise.

    Bluetooth communication being bi-directionnal, you would need to have the radio Amplifier in any device paired with one of these BT832X module or range would be limited to just a few meters with much more risk to get communication errors which would imply even more latency. You wouldn't find such amplifier on a computer or smartphone so this means you would at least need a kind of "amplified bluetooth Dongle".

    Bluetooth protocol also imply lots of communication to make secure exchange betwee various type of devices which means a lot of "data" to transmit beside the useful data (more than half of the data transmitted is about device description).

    We tested the bluetooth option while designing the Sylphyo & Link but results were insufficient for what we expected in term of latency and distance range.

    Hope this helps clarifying things.

    Nordic’s nRF52832 Bluetooth LE SoC combines a powerful 64MHz, 32-bit Arm® Cortex® M4F processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT™, and proprietary 2.4GHz RF software), featuring 512kB Flash memory and 64kB RAM. The SoC is supplied with Nordic’s S132 SoftDevice which also offers mesh capability, enabling scalable networking of the modules.

    @L_Aodyo

    Very good comment, but can you clarify tech details on your protocol?
