Interface and connectivity ICs

Hi. I have two level shifters, ST2378e and ADG3308.But, all of them are not working propoerly. Oscilloscope displayed following video.https://youtu.be/JwTMTi1wS8w I had connected pins properly and checked many times.VL(3.3v), VCC(5.0v) and GND OE pins are right.and 0.1uF cap too. I assumed problem is cross talk ioVL1 with ioVCC1.anybody help me please. I have spend two weeks for this. 

if i use two ,aci_gatt_srv_add_service() will return 0x87 errorbut use only one,it is ok

Hi,There is an introduction on the EVKITST87M01 development kit in the flyer found here: fl2311st87m01.pdf, however, I could not find anywhere online to purchase it. Just wondering if it is available yet?Thanks,Olive

Hi,Is it possible to get the used BLE data channel of the last connection interval?I would like to more or less create a bar chart containing the 37 data channels and rssi values of the GATT connection for quality comparisons. Reading the rssi value with hci_read_rssi() works fine, but I don't know which channel the value belongs to ...I know from other BLE chip manufacturers that this is possible by reading from a special register or memory address, but I could not find anything similar on the BlueNRG-LP module.Thanks, BR

Hi, I'm just starting out with embedded programming & electronics so please bear with me :)I am starting a project based on the STM32F103 Nucleo board. The first thing I want to do is create a USB host port to connect a class-compliant MIDI device.From this link I learned that means the USB class is likely OTG. What I don't understand yet is what I need in terms of hardware. I would like to use a USB type A port. Can I hook it up straight to the MCU pins on the dev board without additional ICs?I ordered this book today which will surely help me with this, but it will take some days to arrive and I'd like to prepare already if I can.

I'm using the BlueNRG-M2 as my processor on an enclosed system with UART communication. My goal is to add the ability to update the firmware via this connection using the built-in bootloader.Using this answer, I am able to activate the bootloader within the application code, but I am not getting full capability out of it using the BlueNRG Flasher utility. The autobaud and Read Memory functions work, but the Write Flash command does not. All of these work when launching the Bootloader on start via DIO7.Initially, I was getting even less ability, but I realized if I reset the High Frequency clock to 16MHz (from the Application's 32MHz), it worked more reliably. My assumption is that there are more parameters my application code changes from their default which the Bootloader relies upon. Is there any list of these requirements, or even better a function within the Keil DFP that will reset the processor to the required state for the Bootloader?

Hello,In different project with S2-LP we want to read raw the for understand and anlyze any data of the communicate between 2 devices.Are we take tke raw data?Is the S2-LP support E527 standart?Thanks Melih

HiAs i can see your eSIMs come with Truphone preinstalled, so i wonder if its possible to use differrent provider.And if it is, how can you do so on examle of B-L462CELL1

I did not see this question answered. I did see a related discussion which motivated me to ask: https://community.st.com/s/question/0D53W00001JVdk5SAD/bluenrg-advertise-while-having-a-connectionI was using the BlueNRGLP DK sample application: BLE_RC_LongRange with two separate BlueNRG NP boards (Server and Client) and a Cell Phone to view BLE advertisements. I am connecting and disconnecting the Client BlueNRG LP board to connect and disconnect from the BlueNRG Server board.I noticed the Server seems to stop advertising once a connection is made with the client but the Server does not explicitly call the Stop_Advertising function in the Server code (verified by breakpoints in the Server code). Question: Does the disabling of Advertising when a connection terminates happen automatically by the BLE stack?

Hi,I am using the Bluenrg-332ac and the eval board BlueNRG-LPS STEVAL-IDB012V1.  I used the 'hci_le_connectionless_iq_report_event' function to extract IQ signals and RSSI. However, the magnitude, which is derived from the IQ samples, fluctuates dramatically even if I put two antennas close (but not stick to each other). (It sometimes can be stable but very sensitive to the position). What is the problem for solving this issue when trying to access the IQ signals?  

This is a question about a TPM IC, if this is the wrong channel please advise as to correct channel. The question relates to the Linux driver for the ST33TPHF2XI2C.Setup:Driver Verion - unlnown - downloaded from GITHUB 06-JUN-2022.IC as ordered: ST33HTPH2X32AHE1Hardware: On a HAT for a Raspberry PI 4, connected to i2c channel 1 (SLC1, SDA1 GPIO pins)OS Linux 5.4.72-v7l Error observed: From dmesg: tpm tpm0: tpm_try_transmit: send(): error -62Generated by: Issuing the tpm2_getrandom 10 command after having reset the ST33TPHF2XI2C via its physical reset pin, which is tied to GPIO 17 on the RPI HAT.Questions:Is this a known issue or has this issue been reported in another bug (my search did not find this issue).Is there a known patch/workaround?Is STMicro supporting this driver - it doesn't appear to have been accepted into the Linux kernel and there doesn't appear to be a lot of activity with it.

Hello!I have been trying to run the example codes from BLE_examples. It works well on BlueNRG_Navigator GUI. Unfortunately, It throws this error to every projects I try to run and deug on WISE-Studio. What must be the problem that causes this error?  

Hello,I configured the s2-lp csma as follow: xCsmaPersistentMode = S_DISABLE xMultiplierTbit = CSMA_PERIOD_128TBIT xCcaLength = 1 cMaxNb = 2 nBuCounterSeed = 0xFA21 cBuPrescaler = 2 I set the rssi threshold at -82 dBm, If the channel is free, it listens for 5.2ms (from the datasheet the Tcca time should be 2.56ms as the datarate = 50kbps : (1/50000)*128*xCcaLength ) and send the packet :If the channel is busy, it listens continuously like in persistent mode until the channel becomes free :It should go to sleep and to Rx mode again twice as I set the max. number of back-off cycles to 2 and I should get the MAX_BO_CCA_REACH Irq from s2-lp. (I did the RCO calibration in init and I use the SLEEP_B mode).Why it does not go to sleep for BOtime after the 5.2ms of Rx ?Thanks,Andy Rochette,Electronic engineer,Inocess [ST Partner]

Hello,I am integrating the BlueNRG-2 module (BlueNRG-M2SA) in a development with an STM32L496VGT6 processor.Currently I cannot communicate with the BLueNRG module.I have done all the tests of my code with the STEVAL-STWINKT1 module, and the minimum configuration to initialize the module and make it operational works correctly, however in the new development the module cannot be made available.I have searched a lot of information on the web, and I think I understand that the default module comes without any firmware, I don't know if this is correct. My native language is not English and I don't know if I interpret the documentation correctly.Considering this, I have tried to connect the BlueNRG-2 module to the STLink-v3 mini, but without success.I don't know if the connections are correct.I would need if someone can guide me.1- Does the module have any preloaded firmware?2 - How should I connect the module to the stlink to load the firmware through one of the BlueNRG GUI or BlueNRG-1_2

Hello,I am using the STEVAL-IDB012V1 module, can you please tell me how I can test it? program it?

Hi.Currently we use SIM7000G and SIM7070G (GSM, NB-IoT, LTE-M, GNSS) modules from Simcom in our projects, using for authentication only a SIM holder with plastic chip, in the old way. We are starting to integrate the eSIM ICs on the boards, to use holder for plastic SIM + eSIM IC + dual SIM card analog MUX, I already did a layout including these 3 things, but still have doubts about the the eSIM. I have sent this email do Simcom support:"Hi, we would like to know if, for SIM7000G and SIM7070G modules, if they are compatible and can work with eSIM chip/IC like the ST4SI2M0020TPIFW of ST Microelectronics, we plan to use this one. Do I just need to connect the electronic signals of the SIM interface of the modules to the same named signals of the eSIM chip/IC? I saw that in Brazil, for the newer smartphones integrating an eSIM, the network operator would generate a QR code to the user, who would scan it with the camera and then the smartphone would write informations in the eSIM chip

Hi team, kindly assist us with below mentioned queries..For the some ST Microcontroller components Datasheet did not specify Thermal characteristics such as junction-case or junction-board thermal resistance. we need these values for the thermal simulation. so can you please provide these data as soon as possible.ST Microcontroller part series mention below: 1] SMAJ15A-TR2] STL13N60DM23] TS924AIPT4] STTH4R02U

We transitioned from BLUENRG-M0L to BLUENRG-M2SP. We did some basic application testing with the X-NUCLEO-BNRG2A1 platform, and we had the example application up and running seamlessly.However, we’ve encountered an issue when integrating the BLUENRG-M2SP with our existing boards. I’m having trouble running the example application. The module and the main controller talk via SPI. While going through the data sheet, I discovered that the BLUENRG-M2SP module must be in Mode “100” pin configuration to be able to talk via SPI with our main controller. Question:Does the module come in “MODE 100” out of the package or is this something we must do at our end. Any clarity on the topic would help us a lot.  

I connected:SIM7000E ->  ST4SIM-200MPIN 30 SIM_VDD -> VCCPIN 31 SIM_DATA -> I/OPIN 32 SIM_CLK -> CLKPIN 33 SIM_RST -> RSTWhen I send the AT+CCID command it returns: "+CME ERROR: SIM not inserted"The same command with a standard plastic SIM card works and returns the right card's ICCID.Did I make the wrong connections? Do I have to do something about RESET denied?Thank you

Dear All, my name is  Mario and I am working the the STEVAL-IDB008V1M board with WiseStudio IDE, version: 1.3.1_R.I want to debug my application with ST-LINK V2 but I have no experience with Wise Studio.Could kindly anybody give me some piece of advice for debug configuration? I configured a debug configuration according to the Wise-Studio instructions but the following error occurs:  Open On-Chip Debugger 0.10.0+dev-01002-g983a95ff-dirty (2020-01-08-15:00)Licensed under GNU GPL v2For bug reports, readhttp://openocd.org/doc/doxygen/bugs.htmladapteradapter assert |deassert [srst|trst [assert|deassert srst|trst]]adapter deassert |assert [srst|trst [deassert|assert srst|trst]]adapter usbadapter usb location [<bus>-port[.port]...]adapter_khz [khz]adapter_nameadapter_nsrst_assert_width [milliseconds]adapter_nsrst_delay [milliseconds]interface driver_nameinterface_listreset_config [none|trst_only|srst_only|trst_and_srst][srst_pulls_trst|trst_pulls_srst|com

We work on BLUENRG2 SDK 3.2.1 as a peripheral device, and we face a lot of 0x22 disconnection reasons; we don't know why it happens.We find that sometimes on sniffer session at the beginning of the connection, the chip doesn't reply to the LL_version_ind, and after the 40s, the disconnection happens. We checked and didn't do any flash operations during that time.And sometimes during a running connection.Currently, we are handling this by reconnecting from the central side, but in some cases, we face the same disconnection over and over, and the only way to recover from this state is to do a software reset. My questions are.1- Why sometimes the disconnection occurs repeatedly?2- How can we avoid this disconnection reason (The RSSI is good)?3- What's the proper solution if this disconnection reason appears? Should I ignore it? Or should we do specific handling?4- Is there another way to handle it without performing a software reset?

Hi STMicrocontroller developer community,I am currently working on a project that involves interfacing of infineon IM69D130 digital MEMS microphone with STM32WB55G microcontroller. However, I am facing challenges in setting up the communication between the microphone and the micro controller and could use some assistance with a Library or Code Sample that allows interface. Any help, advice or resource that can assist me would be greatly appreciated.Thanks and regardsManik Banagar
