I recorded and saved an audio clip (.wav) inside the UFS memory of the Quectel modem (version EM-12).
I would like to copy the clip contained in the modem to my local PC.
How can i do?
Using the command AT + QFDWL = "clip.wav" I only get a binary data output and not the file download.
Thanks to those who will be able to help me

I want to export a database file that is created through a query, from the AS400 machine to my pc in the form of a csv file.
Is there a way to create that connection of the AS400 and my pc through a cl program?
An idea of what I want to do can be derived from the following code:
CLRPFM DTABASENAME
RUNQRY QRY(QRYTEST1)
CHGVAR VAR(&PATH) VALUE('C:\TESTS')
CHGVAR VAR(&PATH1) VALUE('C:\TESTS')
CHGVAR VAR(&CMD) VALUE(%TRIM(&PATH) *CAT '/DTABASENAME.CSV' !> &PATH !> &PATH1)
STRPCO PCTA(*YES)
STRPCCMD PCCMD(&CMD) PAUSE(*YES)
where I somehow get my database file, give the path that I want it to be saved in, in my pc , and lastly run the pc command accordingly
Take a look at
Copy From Query File (CPYFRMQRYF)
Which will allow you to create a database physical file from the query.
You may also want to look at
Copy To Import File (CPYTOIMPF)
Which will copy data from a database physical file to an Integrated File System (IFS) stream file (such as .CSV); which are the type of files you'd find on a PC.
ex:
CPYTOIMPF FROMFILE(MYLIB/MYPF) TOSTMF('/home/myuser/DTABASENAME.CSV') RCDDLM(*CRLF) DTAFMT(*DLM) STRDLM(*DBLQUOTE) STRESCCHR(*STRDLM) RMVBLANK(*TRAILING)
FLDDLM(',')
However, there's no single command to transfer data to your PC. Well technically, I suppose that's not true. If you configure a (SMB or NFS) file share on your PC and configure the IBM SMB or NFS client; you could in fact CPYTOIMPF directly to that file share or use the Copy Object (CPY) command to copy from the IFS to the network share.
If your PC has an FTP server available, you could send the data via the IBM i's FTP client. Similarly, if you have a SSH server on your PC, OpenSSL is available via PASE and SFTP or SCP could be used. You could also email the file from the i.
Instead of trying to send the file to your PC from the i. An easier solution would be to kick off a process on the PC that runs the download. My preference would be a Access Client Solution (ACS) data transfer.
You configure and save (as a .dtfx file) the transfer
Then you can kick it off with a
STRPCCMD cmd('java -jar C:\ACS\acsbundle.jar /plugin=download C:\testacs.dtfx')
More detailed information can be found in the Automating ACS Data Transfer document
The ACS download compoent is SQL based, so you could probably remove the need to use Query/400 at all
Assuming that you have your IFS QNTC mapped to your network domain. You could use the command CPYTOIMPF to copy the data directly from an IBMI DB2 file to a network directory.
This sample would result in a CSV file.
CPYTOIMPF FROMFILE(file) TOSTMF('//QNTC/servername or ip/path/filename.csv') STMFCCSID(*PCASCII) RCDDLM(*CRLF) STRDLM(*NONE)
Use the FLDDLM(';') option in addition to make semicolon separated values, omit it to use comma as value separator.
I am using custom Linux Kernel built through Yocto. I generated sdimg and try to boot it using an SDCARD and it boots perfectly fine. Here along with the Kernel I also use INITRAMFS files. Using config.txt and cmdline.txt file in partition 1, I tell the kernel to load my INITRAMFS file. This procedure is working fine.
Now, I am trying to net boot my Raspberrypi. For this I have another PC which has DNSMASQ installed and it acts as DNS server. I have all the required files in my /tftpboot directory. When I turn on the client RPI, it gets all the files from the server except my INITRAMFS file. I have added the initramfs file name as shown below in the config.txt, but still it is not being requested by my PI. How to make the RPI request for the INITRAMFS file? It just boots up the kernel7.img and thats it !
//appended the following lines to config.txt
ramfsfile=myramfs.cpio.gz
initramfs myramfs.cpio.gz followkernel
Please note that I am not using u-boot.
I was able to resolve the issue. When we do TFTP booting, the first file requested by Raspberry pi(Rpi) is startx.elf, this will be run on the GPU core. Next file that is requested is config.txt. For some reason, if I append the above 2 lines it doesn't work. I read in one of the raspberry pi forums that if the config.txt file is above some size limit, it will be ignored. So I cleared the config.txt file and added just these lines, and voila! Now my initramfs file is requested by the PI and boots successfully :)
I'm sorry for that stupid question but I really can't find what I need.
I made a code to use a ESP Wrover 32 with PlatformIO/VScode and I need to upload the code to the ESP32 (connected to the computer using USB) but I can't find how to select the right USB port to upload the code.
The error is :
Please specify 'upload_port' for environment or use global
'--upload-port' option.
I tried to use the command lines but nothing works.
How can I upload my code ?
Thanks
To find the USB port: Hit WindowsKey-X, select Device Manager, plug in the device and observe what's listed under Ports (COM & LPT) - the one that just appeared has the port in brackets (COMn).
Then in platformio.ini in your PlatformIo initialised project folder, you specify the port as a line under the platform section (env: square brackets line): upload_port = com9 or whatever you got from Device Manager.
I hope this helps.
I have a Raspberry Pi 3 running Windows 10 IoT Core. How can I copy files from a USB stick connected to the device to the local SD card storage? Is this possible using PowerShell?
Ideally I want to do this without the need for a UWP app running on the device and any interaction via a local GUI.
Currently when the device is running its default app and I insert a USB stick nothing happens like it does on a desktop edition of Windows 10.
To further clarify I also don't want to navigate to the devices storage via a UNC path copying files between network locations. The files have to be sourced from the USB stick.
Thanks
You can definitely use PowerShell for this.
Firstly I would use the IoT Dashboard to open a new PowerShell remote management session to my Windows IoT device.
Insert the USB stick if it isn't already.
Then use the following PowerShell command to review the devices local drivers.
gdr -PSProvider 'FileSystem'
This will return a list of all drives attached. Like below.
Note; drives C, D and U are used by the device and system.
Then use a XCOPY in the PowerShell session once you know the drive letter your USB stick has been assigned. Eg. E above.
XCOPY E:\ C:\Data\FromUSB\
This will copy everything from the root of the USB stick to a folder on the devices SD card called 'FromUSB' in the Data parent directory.
Note; creating custom folder on the root of the C drive may not appear to some UI's.
Hope this helps.
I am trying to create a bootloader following this link the things i did are
create a vfd as per given and formatted it.
used partcopy partcopy Boot1.bin 0 200 -f0
then created a config file for bochs emulator.
while bochs emulator loading it is asking for config file when i provide it, emulator stops saying panic
And i also want to know how to know if partcopy is has copied data into floppy. As i try to open the floppy drive after the copy it says format to use( i presume the problem is partcopy only ) .
how can i fix it??
The problem was in configuration file of the bochs.
romimage: file=BIOS-bochs-legacy, address=0xf0000
vgaromimage: file=VGABIOS-lgpl-latest
keep the rom image and vgaromimage in the same place as configuration file. it will work fine .
