kandi X-RAY | modem Summary

modem is a Go library. modem has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

A low level Go driver for AT modems. modem is a Go library for interacting with AT based modems. The initial impetus was to provide functionality to send and receive SMSs via a GSM modem, but the library may be generally useful for any device controlled by AT commands. The at package provides a low level driver which sits between an io.ReadWriter, representing the physical modem, and a higher level driver or application. The AT driver provides the ability to issue AT commands to the modem, and to receive the info and status returned by the modem, as synchronous function calls. Handlers for asynchronous indications from the modem, such as received SMSs, can be registered with the driver. The gsm package wraps the AT driver to add higher level functions to send and receive SMS messages, including long messages split into multiple parts, without any knowledge of the underlying AT commands. The info package provides utility functions to manipulate the info returned in the responses from the modem. The serial package provides a simple wrapper around a third party serial driver, so you don't have to find one yourself. The trace package provides a driver, which may be inserted between the AT driver and the underlying modem, to log interactions with the modem for debugging purposes. The cmd directory contains basic commands to exercise the library and a modem, including retrieving details from the modem, sending and receiving SMSs, and retrieving the SIM phonebook.

How do I silence PyAudio's noisy output?

Asked 2021-Jun-13 at 20:51

I've installed PyAudio and it's working exactly as I want it to, both for playing and recording audio. However, every time I initialise a PyAudio object, it barfs a whole bunch of warnings and error into STDERR and it's making it difficult to sort through my own application's logs. Here's a sample out of an ipython session:

ANSWER

Answered 2021-Jun-13 at 20:51

The problem was that PyAudio loads a bunch of non-Python stuff whenever it's envoked, and it's that's stuff that's printing to STDOUT so it has to be silenced directly. The cleanest way to do this is to wrap it in a context manager that silences STDOUT for the shortest amount of time possible:

What you could be looking for is Local Area Network Ip address:
You could use default function by Node.js os.networkInterfaces()

QUESTION

Cannot reach some devices from different Subnet

Asked 2021-Jun-11 at 17:32

I am a little bit confused about my network setup at home.

This is the setup:

VLAN1 - 172.16.20.0/24 VLAN2 - 10.11.12.0/24

I am in the VLAN2 net (which is my WiFi), for the moment I allowed all traffic between both subnets.

My setup uses a KVM host for most of the services, my firewall lies on this machine and is virtualized (opnsense).

So the KVM network interfaces looks like this:

ANSWER

Answered 2021-Jun-11 at 17:32

I fixed it by myself. The management interface itself was missing a route to the VLAN2 net. Works now :)

FirebaseFirestore.getInstance() and app has stoped

Asked 2021-Jun-09 at 03:39

I run my Android app (based on Java), and it works. Next, I add to my app code:

FirebaseFirestore fdb = FirebaseFirestore.getInstance();

This code I got from the official Android site https://firebase.google.com/docs/firestore/quickstart

App runs, but next the running device shows the message "app has stopped".

I use a device simulator available in Android Studio.

It is my first Android app, and I can't understand what is going.

At the end of your log, just before the initial crash. there is a warning:

Default FirebaseApp failed to initialize because no default options were found. This usually means that com.google.gms:google-services was not applied to your gradle project.

simply adding com.google.gms:google-services should fix any issues you have, if you have issues, ensure your Gradle cache is cleared or run without the build cache --no-build-cache

C++ : why have a return in a if statement?

Asked 2021-Jun-08 at 19:43

I've trying to work out why someone would write the following section of code in a Arduino loop. To me, it doesnt make sense, why have a return in a if statement? Does it just return to the start of the loop and not carry on with the rest of the loop. Here's the snippet of interest:

After return ; or just return; (for void functions) the program exits from the loop and also from function. The function returns (for non-void functions). This statement applies when executing function already is not requeris.

Sending Sensor Data to Firebase using ESP32+Sim800L

Asked 2021-Jun-08 at 05:47

I have a TTGO T-CALL ESP32+Sim800L board and I want to send accelerometer data to Firebase. I am using the TinyGSM library which supports SSL/https connections for Sim800L. I am currently sending dummy data to see if it works but it is giving me a failed flag. Why is it not sending data to Firebase?

...

ANSWER

Answered 2021-Jun-08 at 05:47

I didn't find a lot of resources online, however, I did manage to do this and I made a GitHub repo for anyone who needs help with the same.

Basically as Firebase accepts only Https requests, it is not possible to formulate that on most microcontrollers and GSM modules. To circumvent this problem, I created a php server to which I can send an HTTP POST request and the script can get the data from it and push it to Firebase with a php firebase library.

Issue with debugging usb using usbmon

Asked 2021-May-31 at 08:09

I am using Linux 4.19.55 armv7l on a omap3 processor. On my target there is a usb modem that gets power from a gpio pin value (defined under /sys/class/gpio). There are occasions when I change the value parameter of this gpio pin to bring down the hardware and while doing so I frequently get an error (thrown by musb_handle_intr_disconnect from inside drivers/usb/musb/musb_core.c ) as under:

"musb_handle_intr_disconnect 843: unhandled DISCONNECT transition (a_idle)"

I tried debugging the issue by mounting debugfs and capturing data from the concerned bus by using usbmon. Bus id is identified from lsusb output and confirmed by observing /sys/kernel/debug/usb/devices. I observe that usbmon is unable to capture data whenever the mentioned error shows up. In a no error scenario the usbmon does capture the traffic from the concerned bus. Please help how to debug this issue.

InfluxDB2 Authorization failing for HTTP API

Asked 2021-May-27 at 17:24

I have been trying to externally log data to my home server with a little GSM modem and InfluxDB2 HTTP API- it is far away and needs to be external, just checking water levels and other system stuff.

I am struggeling to understand the correct payload and keys to give it in order for it to accept my data.

I am using an ESP32 and the requests module on Micro Python, using MicroPython_ESP32_psRAM_LoBo.

The GSM library I am using makes everything work as if I was connected to Wifi, I am pretty certian that my problem has nothing to do with the GSM side of things.

The system uses InfluxDB2 and Python3 ( Micro Python to be exact )

I managed to find a solution after days of searching and trying new things.

Basically I used the mrequests lib ( https://github.com/SpotlightKid/mrequests )

With this I managed to get the whole thing working as expected using the following code - Done in Micropython

I did make a free account with No-IP to set my ISP external IP to a URL, I dont think this has a massive change but it is worth noting. I did try the older methods with this new URL and they still did not work.

Here is the new code with the mrequest lib.

ANSWER

Answered 2021-May-26 at 10:15

Okay I have figured it out. The issue is not with the code, at least not entirely. The IP should be "0.0.0.0" or "" for the python listener to bind. Whats more important is that in AWS/Papespace/Linode you pick a static IP. This was very obvious but I missed it since I thought we got Static IPs by default (damn you linode for this bad habit). Moreover depending on your provider, AWS for example needs you to make ports available in their portal. (Screenshot attached)
