Hi I am using a pro Micro to collect data, process it and send it out usb to my pc (for use in processing).
I am currently getting data in through the promicro Serial1 port and outputting it wired through the USB(Serial) one.
Can someone suggest a way to do this wireless between the promicro output and the PC.
I only need 6 feet of range and its line of sight. I currently have a Bluetooth mate gold but can buy something different if need be. I am confused on the hookups since we have Serial, usb, 5v, 3.3v, etc I could use product recommendations as well as a simple hookup method so that I don’t mismatch and burn something out.
Is there a way to go usb to Bluetooth mate gold??? or do I go through serial pins and if so do I need a 5v to 3.3v converter???
You can use the Bluetooth Mate Gold as a usb replacement only if you have a bluetooth enabled computer. You would hook up the mate to your Pro Micro using either the hardware serial port or a software serial port, and then pair the computer and bluetooth device wirelessly. This would remove the need to have a USB cable between the computer and the Pro Micro. If you don’t already have a bluetooth enabled computer, you can buy a dongle (such as https://www.sparkfun.com/products/9434), which you can then plug in to your computer, and use to pair wirelessly with the Mate, which would be attached to your Pro Micro.
If you wanted to hook the mate up to your computer via USB, you would want to use a USB to serial converter, such as an FTDI break out board (https://www.sparkfun.com/products/9873). You will need to make sure you match up the pins correctly however.
The bluetooth mate has voltage regulation included on the board, and can work from 3.3v to 6v, so you don’t need to worry about voltage regulation hooking it up to the Pro Micro. In terms of hooking up the mate to the micro, you will want TX->Rx, Rx->TX, Gnd->Gnd, Vcc->3.3v.
Thanks for the info. But I was wondering if this is possible:
I have a razor Imu from sparkfun that is feeding serial data to my pro micro. The serial stream is then merged with additional data within the pro micro and the amended stream is being output through serial0(USB) to the pc.
If I use the Bluetooth mate gold can I plug the Tx from the imu to Rx serial1 and the tx of serial1 to the Bluetooth mate?
The imu only sends data and doesn’t receive. The pc only receives data and doesn’t transmit.
Can I do the whole thing using only serial1?
Right now I am not wireless so I have serial1 receiving data and serial0(USB) sending data to the pc and that works fine. If I go wireless I think I can only do that either as states above or by using a soft serial library…
Any suggestions? I don’t have any tx pins connected to the imu since it doesn’t receive data and it’s working but I did a test plugging serial1 tx to the Bluetooth mate rx and leaving the mates tx pin unused but no data was being transmitted…
