GRBL
It works wonderfully. I can control a GRBL CNC using an HC-06 BLE (Bluetooth module). However, you need to program the module once via PC or Mac beforehand, which means assigning a name and password. It’s easy to do. I hope there will be updates again soon.
Not connecting to BLE
It didn't work for esp32 boards as it use BLE for connections. Money got wasted.
Hopefully it can
Be configured for 152000 baud rate instead. That’s what my cnc uses. That’s what my Bluetooth module has. Is there a way to do that?
Plasma cutter fix
Works great, easy to use. I used Bluetooth and the app to fix problems with high frequency start interference from plasma cutter through usb. Bluetooth connects easily once set up.
