Waveshare LC29H DA board has stopped responding to commands

My Waveshare LC29H DA module no longer accepts input. It was working fine for quite a while. It’s the RPi hat version and I’ve tried commands using tio from the RPi bash with the jumpers in position B and I’ve tried with the module removed and USB to my computer using QGNSS V2.1 and the jumpers in position A. It is in the last configuration I had which is to only show GGA messages, but I can’t do anything. I even tried reflashing it to the same firmware version and it’s not accepting the firmware either. The RX LED flashes when I send it commands as expected and is off when not sending it anything as expect. Is there a hardware way of factory resetting it by driving a pin on the Quectel module itself low or high?

Hi David,

From your description, it seems that you were failed to communicate with LC29HDA via UART. Please check if the jumpers direction are parallel to LC29HDA module.

You can also share a photo of your setting.
