I'm wondering if a bluetooth 4 remote would work if I have a nrf51822 chip connected to a VESC (hw 6 based).
I found this thing that looks interesting:
I found it cheap, 9$ with free shipping, says it's Bluetooth 4, and already has USB connector, on/off switch and some buttons that I can use for different actions.
Would be great as I could skip the nrf24 chip stuff. Atm I was considering doing a nunchuck version. But this seems a bit more compact, and has more buttons.
Also theoretically I could still use the app on bluetooth when the remote is connected?
I think these types of remotes are used for VR stuff. The ad mentions it's compatible with IOS/Android phones as well, and has some default mappings for the buttons.
