I try to connect to a 3G/4G/5G mobile network using the Telit 5G modem FN990, and I even see an IP address in the logs, however it is not getting assigned to network device wwan0.
the PIN of the SIM is removed, as documented in https://wiki.archlinux.org/title/Mobile_broadband_modem#Remove_the_PIN .
there's basically two routes I took, both of which fail.
a) using nmcli
host:~# nmcli con show

b) using mmcli
host:~# mmcli -m 0 --simple-connect="apn=internet.telekom,user=telekom,password=telekom"
successfully connected the modem

during that, /var/log/messages says:

to me this looks good, but wwan0 is down, and has no IP:

I am using an orange pi to connect to BLE devices, and I would like to use the on board ble interface, I am using OPI3 LTS OS: Orange Pi Focal with Linux 5.10.75-sunxi64

The on board ble interface is hci1, so I shutdown my dongle hci0 and when I try doing a scan using bluetoothctl, I get this error Failed to start discovery: org.bluez.Error.NotReady
I can use the hci0 to do scan though and connect to devices when I bring it up and running, but not on board hci1.
I used the mutex to synchronize the two kernel threads. After running, panic occurred in the system and abnormal memory was found in mutex by kdump.
Here is a simplified code example, You can run it directly to reproduce the problem.
I changed the memory allocation method to use kmalloc instead of vmalloc, and then it worked, Who knows why？

I created small c code to disable Ethernet card device driver's poll interrupt handler on device settings. But its not causing my ethernet card to stop receiving packets. Why is that?
This is the code
#include <sys/io.h>
#include <linux/if_ether.h>
#include <net/ethernet.h>
#include <stdio.h>
#include <malloc.h>
#include <netinet/tcp.h>
#include <netinet/ip.h>
#include <arpa/inet.h>
void main(){
unsigned long addr;
void *data=0x00;//malloc(sizeof(struct ether_header)+sizeof(struct iphdr)+sizeof(struct tcphdr));
addr=0x00000000fe400000+0x000C8;
int x=iopl(3);
outsb(addr,&data,sizeof(data));
}
Base addres that I am using in code 0x00000000fe400000
I check clearing interrupt at ofset 0x000C0 and 0x000C8
Other options are:
0x000C0=Interrupt Cause Read Register
0x000C4=Interrupt Throttling Register
0x000C8=Interrupt Cause Set Register
0x000D0=Interrupt Mask Set/Read Register
0x000D8=Interrupt Mask Clear Register
0x000E0=Interrupt Acknowledge Auto

I use the following code to receive data from an ANT+ dongle I used other software (Zwift, which shows that the dongle actually received data) (Using OS X):
/* Require the config */
require('dotenv').config()
/* require the usb class */
var usb = require('usb');
/* find the device */
var device = usb.findByIds(process.env.VENDOR_ID, process.env.PRODUCT_ID);
/* open the device */
device.open(true);
/* claim interface WHERE IS THIS FOR */
const [interface] = device.interfaces;
interface.claim();
/* Start Polling */
const [inEndpoint, outEndpoint] = interface.endpoints;
inEndpoint.startPoll();
// inEndpoint.transferType = 2;
inEndpoint.on('data', (d) => {
console.log("usb data:", d, " len:", d.length)
});
inEndpoint.on('error', function (error) {
console.log("on error", error);
});
Do I do something wrong?
Underneath you find some loggin, I think I do everything right but it has to do something with node.
