Hi… I’m struggling to get an HL7588 working. I’m pretty sure I’m doing everything ‘right’, and everything seems to work right. Everything sets up and works OK, but the moment I try anything heavier than a ping or a really light web page, the module resets itself. The problem is reproducible going over the UART via a serial port, MBIM mode over USB, and NCM mode over USB, so I’m fairly sure software is not an issue, although it’s possible there’s some AT command I am needing to run that isn’t in the docs. Attached is the output of AT+EXCEPT, which seems to show a crash. I considered it might be a power shortage, but now I’ve got it running on a bench power supply that has more than enough juice, and no change. Out of ideas at this point. I’m on a T-Mobile sim, not AT&T, so perhaps that’s an issue? Any ideas?
Thanks,
Jim
