Bluetooth transmission
(OP)
I was hoping someone could direct me towards a device or suggestion to solve a problem of mine.
I have an inertial measurement unit which can collect and transmit its data via Bluetooth. Normally I'd have this communicating with a laptop which would have either a Bluetooth dongle or built in Bluetooth receiver. However, I need to now send this data to another device which has an analogue input so that all the technologies can be synced together. Previously I was trying to collect data from the two devices the best I could by tapping 'start record' on each device manually, but now I really need a way of starting all the devices by clicking the one main start button so all data is synced perfectly.
So, basically, I need a type of Bluetooth receiver, which has the ability of searching and finding devices (as the IMU has no interface) and then also has an analogue output which I can connect to the analogue input of the main device, I'll then start and stop recording via the main device. I can then decode the packets offline. I'm thinking some sort of audio device which I can use? However, I'm completely clueless.
Any suggestions will be most helpful.

RE: Bluetooth transmission
Your approach of replacing the laptop seems like it would just lead you in circles. You still need a computer in the middle; it might as well be a laptop.
You can of course record analog signals using your laptop. There are endless Analog I/O cards and dongles available. Clever software can synchronize the recordings.

RE: Bluetooth transmission
For an embedded application, a SBC is the obvious choice.

RE: Bluetooth transmission
I could connect to the IMU using the Arduino, leave it idle and collecting packets, then use the main device to start/stop collection of the data off an analogue pin.
RE: Bluetooth transmission
User interface meaning display, keyboard, maybe a mouse or a touchpad. For example, maybe a laptop.
If it's an embedded application, SBC is ideal.
