I'm planning on using either of the 2 products in a new production of our current Wireless (Bluetooth RN42) product. Actually it is a 3rd version since introduction, but thats on the sales side.
What we do is mimic a medical footswitch and or handset unit using BT.
The actions are (depends of the x-ray system) Save or mode (save being a one time pulse per press) and or X-ray or Hi-Level x-ray (these use a security closure as well).
I have written code using arduino under the Teensy devices. All pass are are out in the field.
Yes, we need to certify these, but in time.
Reason the newer system is for battery use. We want to get away from chargers and Li-Ion batteries which currently we need to go through hoops to qualify.
Also, the RN42 and current system kills batteries in less than 40 hrs.
Le can now use alkaline batteries and not worry over Fedex issues. And low power is also a nice item (need less that 20ft.)
Our current BT module setup is 1 for FS, 1 for HS and 2 for the receiver.
If I understand correctly, I could make one unit Simblee or RFDuino a Master or central ?? and the other as slave or peripheral ??
Since the HS and FS mimic each other.
Since I do not have my stuff yet (kits and all), I like to find how to connect the units easily for production.
We program the FS/HS under one freescale and the recvr on another. The other programmers had selections for functions etc.
They can flip banks of switches to do certain functions, but most important is getting the BT modules to talk. When the link, the BT led lites. They do FS first and then HS next to the recvr.
I'm hoping I can do this and lock out other BT devices.
If someone can point me to where to look so I can start thinking on how to program it, be great.
And if I recall, the devices have AES security.. But if we lock it down, should be good too..
