- You Reply: Seeing as how there is basically no other way to contact DFRobot and the documentation for these products is terrible I guess I'm supposed to post my request for RMA here?
- You Reply: Also, I can use AT commands and get board info works ok.
Also it pairs with the Beetle OK.
But I cannot upload any sketches anymore. - You Reply: Apparently discovering this device on a PC is not so easy. My phone can see the device.
Using a BT dongle on a PC, I cannot.
I bought a BT 4.0 + BLE Dongle, still cant see it.
If I plug the dongle into a Raspberry Pi, I can see it.
But my platform is Windows, not Linux..
I bought the BLE Link from DF Robot. I guess is the only option.
It comes in next week. So we'll see what happens then. - You Reply: I dont need it to connect. I just need it to be discoverable. When I scan for BT devices, bluno only need to show up
