Can anyone help me? I don't have any specific experience, but there seem to be several guides for that HAT. Waveshare (the manufacturer): https://www.waveshare.com/wiki/SIM7600E-H_4G_HAT Twilio (SIM provider): https://www.twilio.com/docs/iot/supersim/getting-started-super-sim-raspberry-pi-waveshare...

It's a Waveshare SIM7600E-H 4G HAT.
Jumper on "B" and USB connection:

Which HAT is it? Does it use a usb connection?

Hi guys, I have a problem configuring my SIM7600 4G HAT on my Raspberry Pi 4 Model B. I've tried everything and I can't solve it... I'm following this topic: https://forums.raspberrypi.com/viewtopic.php?t=224355 1. I installed the required software: ...

... going down to as low a 4.92V, but not below it. This is after I have the raspberry pi camera, 2 SG90 servos, a Waveshare Sense HAT and Waveshare SIM7600G-H connected. I wonder why is this low voltage error keep reappearing then. My understanding is that it should come up when the voltage is way ...

There has been progress on this upstream - https://www.spinics.net/lists/linux-serial/msg55220.html - the proposal being to add a new property ("nxp,modem-control-line-ports") that allows none, all, or either half of the GPIOs to be used for modem control. Without the property, the pins re...

The schematic appears to reveal all. They've used GPIO7/RIA as SIM_PWRKEY. RI (Ring Indicate) is an input into the UART when used as a modem control signal, but they're using it as an output. I would have hoped that they'd have chosen DTR (Data Terminal Ready) or similar output modem signal to wake...

I'd suspect that it is patch https://github.com/torvalds/linux/commit/679875d1d8802669590ef4d69b0e7d13207ebd61 that came in at 5.18 that is causing you grief. The SC16IS752 driver now correctly advertises the modem control registers as modem control, not as GPIOs, so SC16IS752 now has no GPIOs inste...

Both Buster and Bullseye support the legacy sysfs route for GPIO control - it's actually a function of the kernel, not the distribution, and whilst the kernel devs have stated it is deprecated, it still hasn't been removed. What kernel version are you now running (uname -a)? Does the SC16IS752 drive...

You do know that WaveShare should be supporting their own boards? My guess is that they are expecting the 8 GPIOs on the SC16IS752 to appear on GPIOs 496-503, making 503 GPIO7, a.k.a. SIM_PWRKEY. Have you loaded the sc16is752 overlay? From https://www.waveshare.com/wiki/Compute_Module_PoE_4G_Board#...

... of working. Then again kernel interfaces can change over the years, so it may have issues. Waveshare also appear to make a module based on the SIM7600. Whilst not brilliant with ongoing driver support, it may be that their instructions are slightly more up to date. https://www.waveshare.com/wiki/SIM7600E-H_4G_HAT

RNDIS is MicroSoft specific protocol, you need more extensive internet searching. And RNDIS might be removed from newer Linux kernels as some people have discovered an unresolvable security issue. Use an open/native Linux protocol I would say. MBIM for example./
