Serial to Bluetooth Adapter - GRIDBluFly

Do not deploy in production.

It’s good to tinker around with, but don’t deploy it anywhere where you need it to actually work all the time.

I like it but

For distance I give it a 5, for connectivity I give it a 2. Here is the problem, if there is activity on the Rx pin then the devices will not connect. The other problem is the CTS pin becomes active after powerup so, if you are using flow control the data will satrt and the device will not connect. I think these can be easily fixed in their firmware.
