GBS Board not responding -- help? #281

Open imacomputa opened 2 years ago

imacomputa commented 2 years ago

Hi, I recently put this together. I'm able to get to the webpage, but it tells me the GBS board isn't responding.

Can anyone see any obvious problems with my soldering? Or does anyone have any suggestions on what to try? I've resoldered almost everything at this point and still have the same error.

I've tested continuity between D1/D2 and SCL/SDA on the clock gen and it was good.

Any help would be greatly appreciated!

P.S. Do I need to connect anything more than power to it to test it?

Thanks PXL_20211015_062850053 PXL_20211015_062858065 PXL_20211015_062907368 PXL_20211015_062925506

On your ESP8266 devkit, you need a power input and a good ground connection. That is enough to make it work. Since you get some logs from the devkit, I think that part is fine.

The devkit talks to the GBS main chip via 2 lines: SCL and SDA. It's possible that these lines are swapped by accident.

The soldering looks okay to me. Maybe try swapping your SCL and SDA cable.

I tried that, but no dice :( I changed the wires on SCL and SDA as well and still no luck.. I don't understand :/

I wonder if you have a defective ESP? Not sure if this would entirely work in this case, but have you tried running an I2C scanner to make sure it can communicate properly via SCL and SDA?

I fixed it! I disconnected my clock board and it worked, it was something with how that thing was wired up. I switched pow/gnd from C41 to C48 and it works!

I connected power and ground for my clock gen to the empty q1 spot.
