Pi4 renamed wwan0 interface..

I'm using QMI interface with a Quectel BG96 modem. This creates WWAN0 interface on the Pi. A couple a days ago, without any notice, on Pi4 (Raspbian Buster) my "wwan0" interface became "wwp1s0u1u4i4" ... ouch! This didn't happen on Pi3 (stretch). Can I reset to default name wwan0? How can be done? :?:

Re: Dotnet 2.2 best way to communicate with GPIO

There are different libs to access Gpio: https://github.com/unosquare/raspberryio Is a wrapper on wiringPI (easy to use) and it's good. Unosquare has also a wrapper on pigpio library I normally use: https://github.com/dotnet/iot This works nice and has a lot of device defined. This comes from Micros...

Re: Pi 3 b+ and waveshare HAT

Hi VanVince,
I think you need to move join PWR to P4 (BS0-H3). This will connect POWERKEY Pin to BCM pin 4 (pin 7 of the connector). Setting pin BCM 4 to 1 will start power to SIM7000. I don't remind if it needs a steady 1 or just a 100ms pulse to start modem.

Re: High percentage of Ethernet Failures - Pi 3B

I read somewhere, that microchip lan951x chip production has changed recently for some weakness in the industrial model due to temperature. I can’t remind where I got the news, but this was not related to Pi.

Re: "Package" Options

To me is not really clear what Farnell, in my country, sells as Computer Module Kit "RASPBERRY-PI RPI-COMPUTE3-KIT Raspberry Pi Compute Module 3 Development Kit" ... They show 2 CM3 boards included with 1 CMIO board, but I'm not sure you get 2 CM modules.

I think you need to declare low level functionality use in the app package configuration. Sorry I can't remind the xml file name at the moment.

I find "Visual C++ for IoT Development" to be excellent. That's for use with the Win10IoT stuff that you can boot on your RPi (that's existed since the RPi2 was launched).
