Hey @agdamsbo Can you please attach a photo of your setup. Looks like I2C communication fails for some reason.
I have the espboard attached to the carrier ESP louder board, microusb from espboard to my computer (macos). I will try again with a different computer maybe if you think its just a communications thing.
It is a communication between module and the DAC that is failing, that's why I'd like to see an actual photo to verify it everything is correct
@agdamsbo in the Revision E DAC cannot pull power from USB (Few customers reported earlier that it blows power circuit on the module). Therefore you need to connect power source to the DAC using barrel jack or screw terminals, keeping USB power for flashing and debugging. Right now your DAC is not powered, as indicated by LED near the barrel jack.
Staring Rev H, USB can power DAC as well, since I changed ESP32-mini for ESP32-WROVER module.
Hi. So now I finally have a little time on hand to revisit this issue. I've had a look at my board again. There is one capacitor (I assume) that looks to be shortening the connection on the mini32 (red circle). And there is another capacitor (again, just my assumption) on the DAC, that is not properly soldered to the pad (yellow circle). I have just marked on the same photo, as uploaded previously. I assume these might be issues (especially on the DAC), that might cause the bad reception I have experienced? Thank you in advance.
Hey @agdamsbo good catch! DAC capacitor is just one out of many filtering power, so it should not cause malfunction. If it were shorted, it would cut out power altogether, so probably it is not soldered. You may solder it back in, if you have soldering iron, or just leave it as it is.
As for the module itself, it is hard to say what it is doing, but I assume it is filtering power. It can affect the network, although that would be quite exotic I'd say. Again, if you have a soldering iron, I'd advise to attempt solder it back in, or remove it altogether and see if it helps. Not much to lose anyway :)
Hi. I tried your webflasher to flash snapclient to one of my Louder ESP rev E boards. I get the following error, which sends the board into a rebooting loop:
