Alrighty then,
Next project is to use BT between 1 master (receiver BT ) to 2 slaves BT (I guess thats what they are called)
The logic is switch closures sent BT to the receiver that will produce a closed (relay contact) for some buttons. Some will close as well but with another relay as security or action.
Some will work in 2 steps. These are ARM and X-Ray.
We have a product out, but the cost of batteries is high, they do not last because of high current (Used in a handset and footswitch)
The receiver gets power from the system ~5vdc or 24vdc (depending on systems)
Long ago I did help with the 1st gen of this product, since it was outsource to some other engineers. Now they have requested me to look into it.
The request is lower battery power (3vdc to 4vdc) using Alkaline off the shelf. They want to have it last a long time .. Currently we suggest to recharge daily. Long time is for months. So BLE with sleep etc.
Hoping to have exchange of the piece of the product. Currently if the footswitch is bad, we need all pieces (Footswitch, Handset, and receiver) So pairing by customer is needed.
Limited range. Since the doctor has the device, he needs not to be far far away. Out current unit will engage x-ray 100's of feet away.. Not needed.
I got the request late last week, so fairly new. The pairing I have an idea, but what to do is another. I'm sure Master and Slave is correct.
So Teensy to control BT (BLE type)
Paul, I'm sure you been getting orders for the one IC.
I think I better change the design on that current product that we use it on (2 boards, 3 IC's total each)
But back to this.
Suggestions on BT modules will be great. Low current ones.. I will look into sources, I have sent email to Pycom and u-blox. ublox has started.
Not a small qty, something like 800 BT modules or more / year.
I have lost count on the IC's bought from Paul so far.

Excuse the confusing post.. Back from Vacation and got in late..
