Interface and connectivity ICs

Hi,I want an application where my device works both Broadcast Role and Observer Role, but y don't know if it is possible. My device shall send Non-connectable and non-scannable undirected events (Broadcaster beacons) and also receive them from other devices (Passive Scanning).I can use this two functionalities in the same BlueNRG-LP or I need two, one with Broadcaster Role and other for Observer Role?Thanks,Daniel

Hello,I am facing a problem while using STEVAL-MKI197V1(https://www.st.com/en/evaluation-tools/steval-mki197v1.html) with Raspberry pi 2 and try to fetch the accelerometer values.I am not able to interface this with Raspberry pi 2. I am using python language for scripting. I am curious if they is anything to be done before interfacing (such as downloading the libraries compatible with Raspberry pi). Since I am new to this process, I would like to know what would be the best approach to interface this sensor and fetch the accelerometer values using python language in Raspberry pi. It would be of great help if anyone has any reference on this and is happy to share.Thanks

Hi all,I'm using for evaluating purpose two NucleoL4 boards w/ X-NUCLEO-BNRG2A1:the first one is running the standard firmware working w/ BlueNRG GUI 4.2.0 (v1.2e - DTM SPI v3.3.0). I setup this board as peripheral;the seconds one is running NimBLE stack on the NucleoL4 and DTM SPI basic firmware compiled w/ LL_ONLY option (in order to use HCI commands).Everything is working as expected: NimBLE is able to scan the peripheral / connect to it / execute pairing.The problem is that after bonding succeed, if I check bonded devices list (on the board running the peripheral role), this is always empty, as shown in the image. As result, if I try to reconnect w/ LTK key just exchanged I got pairing error due to encryption failed.Am I missing something? Similar question was already asked but no answer to the problemhttps://community.st.com/s/question/0D50X00009XkWrdSAF/bonding-problemThanks for the support.Alessandro Morniroli

The BlueNRG-M2SA sends the same advertisement payload on all selected channels. I'm looking for a way to send different advertisement payloads on each channel at the same time (multi-slot advertisement). I need this to send more data via advertisement and I'm looking for a way to use this module to do that.

I have Micron nand flash and it's socket adapter. I want to connect this micron nand flash to stm32f407 microntroller.But I can't do this.I have an example of how to connect nand flash to stm32 like this:https://www.waveshare.com/wiki/File:Open407V-D-Demo.7z .But this example is about samsung nand flash.I need advice and guidance on how to connect the micron MT29F32G08CBADBWP-12IT: D nand flash to stm32f407 controller.

Hello Everyone, I have my own board. I’m using Keil uVision5 and STSW-BNRGLP-DK DK-1.1.0 software package. I have an issue when I try to migrate my own application from BlueNRG-355MC to BlueNRG-345MC. I have followed the steps in the User Manual: Keil toolchain: – in [Projects]>[Options for Target '...']>[Device]>[ST BlueNRG-LP Series]>[ST BlueNRG-LP], select ST BlueNRG-345 – in [Projects]>[Options for Target '...']>[C/C++]>[Preprocessor Symbols]>[Define], add CONFIG_DEVICE_BLUENRG_345 – in [Projects]>[Options for Target '...']>[Linker]>[Misc Control], add –predefine="- DCONFIG_DEVICE_BLUENRG_345=1"I am able to program a simple blinking led correctly, but my issue is when I want to use OTA configuration. For my application I need to program first the firmware BLE_OTA_ResetManager and then program my firmware with Lower or Higher configuration. This works for me in BlueNRG-355. I tried to migrate firmware BLE_OTA_ResetManager and my firmware following th

In the case of communication between STEVAL-IDP003V1 and IO-Link master from ifm. Can I connect STEVAL-IDP003V1 with demo firmware from STM (STSW-IO-LINK) to the IO-Link master from ifm (AL1320) ? or it must use IO-Link master from STM (STEVAL-IDP004V1) to communicate or not ?

I am following this document as reference and am puzzled as of what to do after step 3 of page 12.

I read breif STSW-IOD01 , and  understood that there is a time limit.Is there a method to unlock it?the stack library (runtime limited to 30 minutes) contains the majority of the required IO-Link features,Tanks regards.

Hello.It is a Korean company called LIG Precision Technology. I have a question about TSH344IDT product.I checked the document stating that the marking information of this product is TSH344I.But I'm curious about the marking information about EZxxx.Also, please let me know when the production was stopped.Thank you.

Hi.We are developing the 315MHz band using SPIRIT1.After trying with several chips, some chips can and cannot calibrate SPIRIT1.For chips that cannot be calibrated, we solved it by putting a waiting time of 5ms several times while setting the register value before calibration.In this way, is it necessary to put some waiting time in the register value setting and calibration of SPIRIT1?

I'm using STM32L053 to send an SPI data to other compenet. i don't know if the data has been send or not. I don't have an oscilloscope to see the signal.what should i do to know if the data is sent correctly or not?

I have received a response on this which mentions pins 1, 6 & 15 as O/C. What about nReset (pin 8) and AntOff (pin 14)?

The databrief for this kit doesn't explicitly state that it comes with an antenna, just "SMA female connector".Can someone confirm if it ships with an antenna? If not, any suggestions for one that fits it?

I have an STEVAL-IDB008V1M connected to my Windows 10 PC by USB. I have installed the BlueNRG-2 navigator v.3.2.2. After flashing "Hello, World," a terminal sometimes pops up, and other times I must open one myself. Either way, no text is being printed in the serial terminal.When using PuTTY, I have configured the settings to be: 115200 baud, 8 data bits, 1 stop bit, no parity, no flow control. Is this correct? The user manual never states what the serial terminal settings should be for these micro-examples, only for later examples.Thank you for any suggestions you might have.

I have a few X-Nucleo-IDB05A1 boards, and when I test them on the X-Cube64 board, some work and some don't. So I checked it, and like the attached picture file, the Trace Code and Bulk ID are different.Trace code XN915011 is fine,11540270 doesn't work at all.What's the matter?

I am having STEVAL-IDB011V1 board. I am developing the battery profile for that i have refer the ADC_Battery_sensor and BLE_sensorDemo example but the code is stuck in below loop. Please let me know what is the issue in firmware. Is the issue is in ADC initialization.

I'm not sure if the failure is in tx or rx.The full generated project is attachedtested on dual nucleo-f401RE+S2868A1 boardstest protocol: reset both boards, click few times on blue button of a board, and see it just blink twice on the other board.I have no clue where to find the problem, I just see the example is failing fast, and when pushing a button the app think it does send radio frame.(it goes to: SM_STATE_SEND_DATA, SM_STATE_WAIT_FOR_TX_DONE and back to SM_STATE_START_RX )stm32cubeide 1.8.0SUB2G lib+example: 4.2.0

I'm struggling with an issue regarding the number of GATT services, characteristics and descriptors in BlueNRG by STM. I have currently set 6 services and 8 characteristics, minimizing the number of attributes for each service inside maximum_attr_records​ variable as input of GATT function aci_gatt_add_serv().Everything works fine until I add the seventh service or the nineth characteristic: the GAP does not initialize and the communication is stopped.I imagined that is something connected to the number of attributes/services/characteristics used in my application that require all the GATT stack memory, but it seems weird.Is there a way to increase this maximum value using the BlueNRG protocol?BlueNRG-2, STM32CUBEIDE 1.7.0, X-Cube-Ble 3.2.2

Hello community,I configured the uart dma in my project based on the project example USART_TxRx_DMA_Init, and stuck in frame errors, one of the errors is the end of the string seems to be swapped.Sometimes there is no problem the end of the string is \r\n (0x0D 0x0A) and sometime its 0x0D 0xA0. This is because the dma ends before uart has finished, and another string is sent.I modified the example project so that it continuously sends with few ms delay between each, and no error.How to prevent dma from overwriting previous string data without delay ? (using another IT ?)I got the same issue with the example project and STEVAL-IDB011, you can see in above image, the spike is the dma IT.
