 Hello,The firmware for the P-NUCLEO-LRWAN2 gateway is currently provided as a binary file named "st-nucleo-lora-gw-at-fw-v2.1.7-eu868-TTN.bin." I am very interested in obtaining access to the source code to develop a modified version of the firmware for personnal uses.I understand that the P-NUCLEO-LRWAN2 kit is obsolete, but I continue to use the gateway as a packet forwarder for instrumentation and experimentation. Unfortunately, it does not support the latest version of the Semtech UDP protocol, which requires a TX_ACK to be sent after transmitting a packet (as specified here: https://github.com/Lora-net/packet_forwarder/blob/master/PROTOCOL.TXT). This limitation causes issues with multiple network servers. I would like to address this issue myself and make a few other minor modifications.Could you please let me know if the source code is fully closed, or if there is a way to obtain it?Best regards.

hello.This is my first time using TCP communication, my first time using ESP8266, and I am barely able to follow STM32. There's something I want to make, but it doesn't work out, so I'm posting it here.After configuring the ESP8266 with the AT command (Server), if you request data from the server using the Modbus poll program on your PC, the command will be received successfully.If you look at the network traffic, it comes in like this:"ec fa bc 1e fd 74 04 7c 16 a2 d5 c5 08 00 45 0000 34 4b 33 40 00 80 06 00 00 c0 a8 02 9c c0 a802 64 e2 53 01 f6 00 0e 59 85 00 00 19 71 50 18fa f0 86 77 00 00 00 11 00 00 00 06 01 03 00 0000 0a"Looking at RxData in STM32"0d 0a 2b 49 50 44 2c 30 2c 31 32 3a 02 ef 00 00 00 11 00 00 00 06 01 03 00 00 00 0a"It comes in like this."00 00 00 11 00 00 00 06 01 03 00 00 00 0a" This is Modbus data, and the values ​​in front are written as "\r \n + I P D , 0 , 1 2 : \v ]", but I don't know what they mean.Anyway, I analyzed Modbus data and created response data.The

I understand that ADC Linear Calibration is performed during device production and the values stored in the System Memory.However, I have been unable to find any documentation on where the 6 values are stored.Also, are their 6 values per ADC device (ADC1, ADC2, ADC3) or do one set of values apply to all 3 ADCs? 

Hi,I want to use BLE mesh to reach my application, the requirements below.I have a root node and need to send the custom data to each client node and need to read the status from the client nodes.The client nodes don't need to communicate with each other.The client nodes need to send back the custom data to the root node regularly.The user can use a Mobile APP to control the mesh network or through the root node by PC.The root node can be removed when the mesh network is established and finished configure each client node. If needed, the root node can rejoin the network.Based on the above needs, are there any related projects that can be referred to?Please help me and give the suggestions.Thanks.

Hi I am new to the WBA series and am currently working with STM32WBA55G-DK1 board to implement the audio examples.I have a doubt, Can I implement my own custom profiles for sensor data transfer along with the audio, so that, when connected to an app, I will have audio as well as data services?Where will the custom GATT services sit? How to implement both the Host stack and Audio stack? Also,I realised that the DK board doesnt have many peripheral example, which, on other hand are provided for the WBA nucleo board.  Can I implement those codes in the DK board?@STTwo-32 @TDK  @KDJEM.1 @IssamosThanks in advance!

HelloGlobal definition of pointers:unsigned int *uIntUtilityTmpP; unsigned int *uIntP_2_UtilityTmp;In a function I would like to initialize them with absolute values:*uIntP_2_UtilityTmp=0x15; *uIntUtilityTmpP=455; uCharUtilityTmp=62; sprintf(print_string,"1 -> *uIntP_2_UtilityTmp: 0x%x, *uIntUtilityTmpP: %d, uCharUtilityTmp: %d\n", *uIntP_2_UtilityTmp, *uIntUtilityTmpP, uCharUtilityTmp); writeMessageRS232(PRIMARY_COM_PORT, (uint8_t *)print_string, strlen(print_string));The printout on COM port shows following:1 -> *uIntP_2_UtilityTmp: 0x1c7, *uIntUtilityTmpP: 455, uCharUtilityTmp: 62Problem which I have here is that both pointer have the same value. When I write to *uIntP_2_UtilityTmp=0x15 I can see in debugger that also *uIntUtilityTmpP was refreshed with the same value. The same is the case in the next step when I write *uIntUtilityTmpP=455; and then variable *uIntP_2_UtilityTmp gets the same value in this case 455 which is 0x1c7.Why this is so? What to set in compiler or in mi

Dear, I am looking for this component (diode) that I cannot identify to check its datasheet  THANK YOU SO MUCHGREETINGS 

My STM32H747 (Portenta H7), with latest CubeHAL H7 drivers, fails on USB streaming, as USB audio from MCU to host (USB Digital Microphone).It enters in USB FS IRQ handler all the time the branch with the "Incomplete ISO OUT". Nothing comes out to PC."Funny" is: if I let it run for a very, very long time - suddenly it works: the PC gets now my USB audio.It tells me: something wrong with the ISO stream and the frame counter (or this "even and odd" issue, as found in Internet  threads).The only solution I have found: go back to an older version of the file "stm32h7xx_hal_pcd.c".Now it works (actually, I am aware of this issue since years, I took this file from an older project where it works).OK, STM provides examples, e.g. X-CUBE-AUDIO, but it is not for a H7 MCU.Taking the USB files from there seems to be risky: it is not for the same MCU (even I would modify all includes of H7 header files), And a "Diff" on these files shows me some "dramatic" differences (where I cannot make a de

Hello everyone,I'm new to STM32 programming and currently working on a project that involves using the AMT-103-V encoder with an STM32 microcontroller. I would greatly appreciate any help or guidance on how to effectively interface and read data from this encoder using STM32.I've been exploring the datasheets and resources available, but I'm looking for practical advice or sample code that could help me get started. Specifically, I'm interested in how to set up the hardware connections and initialize communication protocols such as SPI or I2C if applicable. Additionally, any insights into how to interpret the encoder's output or handle specific commands (like BiSS-C protocol commands) would be incredibly helpful.If anyone has experience with this encoder or similar projects with STM32, I would love to hear your suggestions or see any sample code snippets that could serve as a starting point. Understanding how to integrate this encoder into my STM32 application effectively is my current

Not just an idea, something to verify:"PDM microphone via USB or Network"Instead of doing the PDM2PCM conversion (inside MCU) - send the PDM bit stream to a host PC at it is. We can do the PDM to PCM conversion, e.g. with Python scripts, on a host PC. Get the PDM bit stream directly, e.g. via USB as "Audio Input" and Python "sounddevice" or "pyaudio". Do the conversion on PC (which is faster, more flexible, allows to investigate the PDM MIC signal, e.g spectrum, which Delta-Sigma order, ...).I have checked:Actually, a PDM microphone should be similar to DSD. With 44.1 KHz sampling frequency, used for PDM MIC, it should be quite identical to a DSD64 audio bit stream.Can I send PDM (without conversion into PCM) directly (without any filter used) via USB or Network?Sure, I can! (via network anyway not a problem).As USB, I need:48KHz audio sampling frequency, with decimation 64 - I get 48 * 64 bits PDM = 3.072 MHz (on SAI, PDM MIC).with stereo = 6,144 bits per 1 msbut packed as bytes: I ne

I am using the STEVAL-STWINBX1 development board and have downloaded the FP-SNS-DATALOG2When I open the help file FP-SNS-DATALOG2_Package.chm (in STM32CubeFunctionPack_DATALOG2_V2.1.1\Documentation) it appears to be empty other than the index...Why is the help file empty, how do I get it to work ?

Is there a MATLAB script to plot and export the .dat files saved by the STWINBX1 datalogger ?

Hi, I have a NUCLEO-WBA52CG dev board.I am seeing an issue whenever I do hard reset for the first time after power-on.After power-on my the loaded application works as expected, after a hard reset(using the button), the clock configuration seems to be about 44% what is expected. This behavior can be observed with the BSP example for the board. Basically the delays between LED blinks are longer. I also had an application that prints something via UART and the output was garbage on my serial terminal until i adjusted the baud rate accordingly.I have not fully tested what else is non-functional but other peripherals may also be affected since my other application(Using SPI, DMA, interrupts, etc) was no longer working as expected instead of just running slower.Interestingly, a second reset fixes the issue. A third reset goes back to the problem state, and then another reset it is again working as expected.

I want to use a STM32G4 device in a new project but I was disappointed to find the USB implementation only supported Device mode.What is the hardware (implemented in the MCU) that make it capable of host mode from device mode (OTG supports both)?  Without knowing the answer - can the missing hardware be implemented in software using the USB cell made for just device mode?  Thanks.

STM32CubeProgrammer version 2.16.0Target STM32G0B0RET6, device ID 0x467, Rev Z, 512KB flash, bootloader 0xD0When loading a large bin file (425kB), the programmer tries to erase 65364 sectors! There's only 256 sectors in target, and the image only needs 212 sectors erased.When using an ST-Link SWD interface it gets past this (albeit erasing entire flash) and programs the flash OK, but when using USB it just locks up.It doesn't happen with smaller files that will fit in bank 1, just larger files that require 2 banks.If I do a full chip erase first, then tick "skip flash erase before prog" then it avoids this problem. However I need to preserve config data at top of flash, so this is not a good workaround.I think it's a similar problem to this post so I replied to that, then thought I should start a separate thread.Here's some basic logs in case it helps.
