However, for myself (and I suspect others), I don't need yet another app to do something. I want to push a button and be finished in 1 second for something like a desk. Cognitive load on this should be zero.
On Android the free (as in money) NRF Connect application lets you browse the services/characteristics, tells you which ones are read/write/notify, and snoop+send data. I also had to use the 'Bluetooth Snoop Log' setting in Developer Options and open the log in Wireshark to sniff some of the packets that the app sent. The log contains timestamps so you can wait 10 seconds between operations to make it really easy to identify what does what. All you need in Wireshark is a filter like 'btatt.uuid128 == ff...:ff' to filter to just the characteristic you want to sniff.
Given the prices it gets at, why not just go for a non-ikea desk e.g. a basic Jarvis is actually cheaper than that.
It can be controlled via Bluetooth with an app on your mobile. It is a much better option in comparison to Bekant in my opinion. The tabletop on IDÅSEN is much thicker too, making monitor mounts safer to install. If you are on the market for a standup desk with good value, pay $100 more and buy IDÅSEN instead of the Berkant desk mentioned in the Tindie campaign.
