sfx_u8* version_m; sfx_u8 size_m; retr_err = MCU_API_get_version(&version_m,&size_m); This works for retr_err = ADDON_SIGFOX_VERIFIED_API_get_version(&version_a,&size_a); retr_err = RF_API_get_version(&version_r,&size_r);but not for MCU_API_get_versionPlease help. Thank you
I am designing a device using the STUSB4500 in QFN-24 package. In the datasheet, pin 3 is both specified as NC and VCONN.The pinout says it is NC, but in any example schematics, this pin is shown as VCONN.In different resources, this pin is either being treated as NC, or connected to GND.The STREF-SCS001V1 reference design has pin 3 connected to GND.Below are some reference documents, together with revision dates and how this pin is treated on schematics:The STUSB4500 datasheet was revised on 03-Jul-2018 (pages 3, 4 - NC)The STREF-SCS001V1 was revised on 31-Jul-2018 (page 2 - GND)The UM2533 was revised on 08-Jan-2019 (page 3 - GND)The STEVAL-ISC005V1 is not dated, but the schematic is the same as in the datasheet (page 1 - NC)Which approach is the correct one?Cheers!
I have reference H/W design by X-NUCLEO-S2915A1.It has still have "IRQ_LOW_BATT_LVL" and not send TX data.-Pin1, Pin7, Pin10, Pin15 is 3.3V Level.Could please let ms know if you have any recommend my check point...
I am using the STM32 Iot Node discovery kit, and I frequently get ES_WIFI_STATUS_UNEXPECTED_CLOSED_SOCKET errors. The wifi reports it is still connected, but obviously there is an issue..How do I properly handle this error and establish a good connection again?disconnect and re-connect the wifi?Soft reset the wifi module?Hard reset the wifi module?Something else?The error occurs frequently and is from en.fp-cld-azure/STM32CubeFunctionPack_AZURE1_V4.0.1/Drivers/BSP/Components/es_wifi/es_wifi.c:1843I also frequently geten.fp-cld-azure/STM32CubeFunctionPack_AZURE1_V4.0.1/Drivers/BSP/Components/es_wifi/es_wifi.c:1976 :AT_RequestReceiveData failedand I don't know how to handle it
According to the datasheet, it is possible with ADC to sample voltage up to 3.6V, even with lower VBAT, if proper attenuator.I'm powering the MCU with 2.5V and feeding battery (up to 3.6V) to ADC1 pin. No matter what setting I use, the ADC is still sinking a lot of current - approx. 40 uA for ADC1 pin and more than 1 mA for ADC2 pin.I've even tried setting CHSEL to 0 that should result in input connected to the ADC, but it is still the same.My standard setup is ADC1, CHSEL=2, OSR=0, single mode, REFSEL=2, PGASEL=2.Is there anything I'm missing in the specs?
Hello , I want to compile the BLE_ChatMasterSlave exemple from STM32L library of the BlueNRG1-2 DK package to test the network coprocessor architecture . The fact is that the code is only compiled with IAR. Is there a way to compile the project with Atollic True Studio ? Thank you .
Hi, I'm using BLUENRG-2 chip with DTM (UART) FW as a BLE module for my STM32 processor. In general everything works - I'm able to set-up profiles, establish connection with central, send notification and receive data from characteristics. To achieve that I'm using example code generated by BlueNRG GUI package - I'm sending commands to trigger notifications and advertising - I'm reacting to events generated by BlueNRG to receive data. So to summarize - i send HCI Commands and receive HCI Events. However, from time to time, BlueNRG-2 sends me the HCI Command OPCODE=0xFD06 (which I identified as Aci_Gatt_Update_Char_Value) with handle of my profile - it seems handle of target char is not existing. It surprises me a lot because I thought that I'm the master here and I should expect only events... Moreover commands are just dropped by example code - only events are processed. What could be the reason that BLUENRG generates such command ? is it safe to drop it as in example code ?Best,Wojcie
Good day. This is IC programming manufacturer.We have to support this BLUENRG-248 QFN48 on our IC programmer. Could you help to provide the programming spec to us for development?Please let me know if we need to sign NDA.
On the WE-Website is a picture of "100W USB Power Delivery Demo Board V1" in the Flyer of the USB_TYPE_C_Devkit. I can however not find this anywhere. I then looked into the P-NUCLEO-USB002. However I can't find information on how much power this module can actually deliver.I want to attach a 100W load to EVAL-SCS001V1 and power it with said PD source.Would be nice if USB002 worked, since I need NUCLEO-F072RB to configure the SCS001V1 anyways.
Hello,I want to use TDA7708 in my project but, i couldn't find any reference design. How can i find reference design or application manual ?
Hello everyone,I'm trying to use a KSZ8863 to monitor ethernet traffic. the KSZ8863 is connected to a STM32F767 via RMII.Im using the STMcubeIDE lwIP stack.I have no problem getting a ip-adress and ping the STM32. Also the SMI interface to the KSZ seems to work - so I can read and write all Registers.What does not work:I have normal data transferns between Port1 and Port2 but its not mirrored to Port3 (STM32).So I want that all the data send from Port1 to Port2 is also send to the STM.With my understanding of the KSZ datasheet I set Port3 as Sniffer Port (register 49 bit 7 = 1)and Port 2 as Transmit Sniff (Register 33 bit 5 = 1)But that has no effect.I looked with a network analyzer onto the RMII interface and there is nothing on the Rx lines. Only Broadcast messages (and the ones adressed to the STMs IP) are received by the STM.Any Ideas what I'm doing wrong? Or what is missing?Any help is welcome :)Cheers
Hello,Iam using HCF4010 for my project. Can i use this as CMOS to TTL converter?Also for high speed switching or for high speed signal is there any issue for using the same ic(Please find the attached image,4 GPIO & 2 spi lines were used)
I am using the Discovery IoT Node kit with (mostly) base software. It looks like it makes a connection OK, and the SendEventAsync accepts the messages it wants to send, but I don't see any data in azure iot central.I checked using a virtual device on my PC and it connects and sends data OK.A couple things I've checked:The connection string is correctThe field name being serialized and sent matches what azure is looking forSome other things that I don't know are related.The code had been getting stuck on the while loop below... I wasn't sure if I'm supposed to set azure up to send something to the device when it is connected and that is why it is hanging... but maybe this is related? while(ReceivedDeviceTwinProperty==0){ IoTHubClient_LL_DoWork(iotHubClientHandle); HAL_Delay(100); }Also, the device sends 214 messages and then hangs... it's done this a few times...I haven't worked on tracking it down yet... I'm assuming it should be able to run and transmit data "forever".Below is outp
I suppose there are some mistake in Blenrg CodeStatement: * @arg FIFO_LEV_1_64: interrupt when Tx FIFO becomes <= 1/64 full = 1 ... at the line 440 of blueNRG1_uart.c is misleading. In accordance to datesheet instead of "full" should be "empty". In the datasheet for the TXFIFO buffer: 000b: Interrupt when FIFO ≥ 1/64 empty. (page 67 of BleuNRG2 datasheet).
Hello,Iam using HCF4010 for my project. I tied both vcc and vdd into 5V. The 6 input to the ic is connected to an esp32 chip(3.3V). Is there any problem while using like this? Is it take more current from the inupt side? As per the above connections, i got an 5V output for each 3.3V input signal. But it affects the internal voltage produced by the esp32 chip, where that voltage is used for code storage.Warm regards, Monisha om
Hi there,Seeking lowest possible energy, what is the difference between the two operation ?Do the configuration remain on the peripheral if I cut the clock ? (then restore it before transacting with the periph)Side question: What to avoid in order to prevent a shoot in own foot ? (I guess cutting flash controller clock is a Bad(tm) idea).Thanks.
Hi,The BlueNRG-2 describes compatibility with the 5.0 spec. but I've been unable to find specific mention of the longer range via lower bit rate 500kbps or 125kbps and Forward Error Correction (FEC).Is this long range mode supported and if so can you point me to some documentation?Thanks!jay
Hello, in our project we use SPBTLE-RF0 modules. Unfortunately we did not pass RX test according to EN300328.On the module the newest sw is running. The module is located in the directmode and is controlled via hci. I have not found any radio report on the website.The tests were carried out at 7Layers. I am open to all ideas and recommendations on which this can be. The module is operated directly by 2 AAA bateries.Thank you for your support
I tried 3 different import options, but STM32CubeIDE disables the build icon, and there is no .project file. It appears that the firmware was created in a different development environment, but all the documentation says nothing about it.
Hi,I'm starting to play around with ST BLE.I'm using X-NUCLEO-IDB05A1 on NUCLEO-F401RE.I've just followed the "Getting started" https://www.youtube.com/watch?v=AIJA4yRxuP4 I've drag .bin over the icon: NUCLEO_F401RE (C:\Users\andre\Documents\BlueNRG MS Stack\en.X-CUBE-BLE1\en.X-CUBE-BLE1\STM32CubeExpansion_BLE1_V4.4.0\Projects\STM32F401RE-Nucleo\Applications\SensorDemo\Binary)Board is fleshed and LD2 is greenBut BlueNRG App v1.1 doesn't recognize any device.What could I check to find the problem?Thanks a lot
Now in my new projext ,I used a ranging chip VL53L0X in the design,but I don't know how to read and write the VL53L0X register directly in my C program , can you email me a VL53L0X register description ? Sincerely hope to get a reply ,my eamil is 1851834739@qq.com
