I went to the recovery guide https://docs.bluerobotics.com/ping-viewer/firmware-update/#device-recovery to try and solve the issue I’m having with one of my Ping Sonars and the webpage wasn’t useful; it’s under improvement. I also referenced Ping1D not detected by Ping Viewer Ping Viewer doesn’t the detect the Ping1D automatically. When trying to connect manually Ping Viewer doesn’t show that device is available. I know the BLUART USB to Serial and RS485 Adapter and the Micro-USB to USB-A Cable I’m using works because I utilized them to connect another Ping Sonar I have to Ping Viewer.
I tried swapping the TX and RX wires and that didn’t work. I opened the device to see if LED is blinking and the green LED wasn’t blinking. I believe that I have to reset the firmware. I know that I hold the “BOOT” button down (I don’t know how long) and use Ping Viewer to upload new firmware. What am I missing?
