Hi,
I created a stack composed of a pi 4, a pijuice ups, an lte base shield ver2 and a cluster hat. Everything worked perfectly. Switching the lte module to the base hat, I get a message that cluster hat is not present.
Trouble shooting, I tried the lte hat on usb only (hat not stacked with the rest) and all is working. I also tried with all the trace of the gpio’s cutted on the lte hat but it did not worked. I suspect something is wrong with the uart pins (trace not closed with weld).What else is different between lte hat and lte shield that could cause this issue?
Update:
Chris from cluster Hat suggested a conflict between lte hat and cluster hat eeprom’s.
