Hello, could someone suggest me a GPS chip that I can use it with STM32F7 MCU, it should target MCU development not general purpose operation system like Linux or Android and has driver to be implemented inside the MCU firmware.Best regards,Moamen

Hey there,-I just buy STEVAL-IDB007V2 BlueNrg-1 board to develop application. I downloaded and set up BlueNRG GUI v3.0.0-When connect the board to PC i open the BlueNRG GUI v3.0.0. Port is seen where the ST DK is. -But when i try to click Open. It gives me this errors:1)When i click okey warnings continue:2) And when i click okey last error occur like :3)When i click Tools->Flash Motherboard FW it expecting from me a .hex file. Where can i download the latest firmware version of my board's motherboard.Thanks

Hello,I have successfully integrated the wifi module with my controller( STM32F429IGT6) but now I a facing a problem in sending and receiving the data to Cloudmqtt through ESP8266. Here I have attached the code which I am using for your referenceWhen I tried to publish a data to Cloudmqtt using CIPSEND command it is showing NO TAIL, ErrorCan you help me with this.?

CR95HF development software v2.3.0 recommended update firmware from version 3.6.0 to version 3.7.1, but not describe how!! 

I happend to notice the driver in linux kernel treedrivers/media/platform/sti/hvaAnd i want to know how to use this driver in usespace, i have been looking for the SDK for days, but end with nothing. so anybody knows where Can i find SDKS for STiH410 series?Thanks a lot

Posted on July 17, 2016 at 20:09I am trying to connect a BlueNRG device to a PC running windows 10.  The PC discovers the BlueNRG but when I try to pair the device the PC says that Something went wrong.  The software in the BlueNRG is a modfied version of the software provided by ST as a demo for connectivity and works well with Android.  Can someone provide some information on what to look for.  A search via the WEB did not help me find any answers. #bluenrg-pc-connectivity

I'have imported the I-Cube LrWan (LoRa) library and end_node example into SW4ARM (Eclipse). This example is working (With SX1276MB1MAS) module. By default it sends a LoRa packet with SF12. Where (which .h file) can I set this Spreading Factor?? to SF7 for example. I have been looking through the code for hours now.

Hello,I have problem with transmitting data from Spirit1 to SP1ML USB dongle module. Al registers are exactly the same on both modules. No matter what I'm sending (via Spirit1) 96 byte ASCII string or even 8 byte one on receiving side (SP1ML) i get 192 bytes of random data. What could be wrong with my initialization procedure?So far my initialization procedure is quite simple and contains:Check if ID number is correctWriting data to configuration registersFlushing TX FIFO with flush TX commandSending string of ASCII characters to TX FIFOChecking if massage that FIFO contains have correct sizeTransmitting data with TX commandAm I doing something wrong or missing something? Let me know. Thanks in advance.Best regards.

Hi,I want to burn the SPWF04S - ST wifi Dongle with specific Fw version 170726-b7ac1ba-SPWF04S version.where can i find the specific Fw version 170726-b7ac1ba-SPWF04S ?

The BLUENRG2 SPI sample is set for 8 bits. When I try to change the data size using data size to SPI_Data_size32b, it does not work. Anyone has run into the same issue?

Hello,We are developing a product that has some circuitry permanently powered inside a sealed enclosure. We need to determine if we need a load switch for the host processor to cycle power to the BLUENRG-MSQTR BLE module in the event that the BLE module locks up to the point that the SPI does not work.The datasheet says that in Reset mode, the BlueNRG-MS is in ultra-low power consumption: all voltage regulators, clocks and the RF interface are not powered. Coming out of reset, "the BlueNRG-MS is fully operational: all interfaces, including SPI and RF, are active as well as all internal power supplies together with the high speed frequency oscillator. The MCU core is also running. The core is the internal Cortex CPU core and it says the core is “off�? in reset mode. Although it is not stated, this implies the CPU is in a reset state, not halted.Can ST please confirm that toggling the nRST pin actually performs equivalent of disconnecting and reconnecting power to the modu

Posted on October 05, 2017 at 12:38Hi,sometime I get the error 'Failed to resolve name'. I always call the same address - so the address is valid. If I get this error I have to reset the module.What failures cause this error?BR,Flow

While working on a standard OTAA Rejoin procedure for our application I've noticed the LoRaMAC callback primitives are all fixed in the LORA_Init() function. When I want to catch the event the MAC layer signals the reception (or not) of a server ACK on a confirmed uplink this must be hooked in the primitive "McpsConfirm(...)". This would mean a modification of this file, but with version control in mind I would prefer to be able to use a public struct/variable or user-definable callback (e.g. like the LoRaMainCallbacks).Am I overlooking an obvious solution? Or has this already been discussed and discharged as unwanted?I'm looking forward to reading your reaction =)

I'm trying to read the temperature using the MLX90614 sensor, however I can not get into the project. I'm using the I2C communication protocol and the code provided below, and I get the value 0 when I read it in the variable buffer.After many attempts my doubt was to verify if the sensor was actually connected correctly, then I used the following command:Which returns HAL_ERRO. What should I do to read the temperature correctly using this sensor and the stm32f1 ???

HI dears,I am working with BLUENRG-MS stack using spbtle-rf.After some tested I noticed that there is a limit to the number of services/charectiristics I can add the BLE.How can I calculate that limit or when I can find this information ?Regards

According to the description of CCA_PERIOD[ ] on page 41 of the ref manual (DocID 022758 Rev 10) , Tcca is the time between two successive CS samplings but the CSMA flow chart on page 40 indicates that CS sampling is done continuously for Tcca duration. I guess the flow chart is wrong. We urgently need to get SPSGRF-868 working for a European customer. Also please confirm that the Tbit is (1 / 34.7 kHz) = 28.818 micro-secs. 

Nowadays I´m working development a converter in PLC (CCS) to CAN (CHAdeMO). But I don´t have sure about the best Evaluation board for this task, because I don´t know frequency in EV and EV supply. I thought EVALKITST8500-1.https://www.st.com/en/evaluation-tools/evalkitst8500-1.htmlBest Regards

I want to place the BEACON mode and THROUGHOUT mode into one project on BLUENRG-1 hardware platform, and send AT command to switch seamlessly between two modes. Now I know how to work in one mode, but could not switch mode. How to do this?

Just was wondering, would a S2-LPQTR module be able to be used as a transceiver to create a microcontroller based EPC Gen2 RFID (860-960MHz) card?"An Interrogator sends information to one or more Tags by modulating an RF carrier using double-sideband amplitude shift keying (DSB-ASK), single-sideband amplitude shift keying (SSB-ASK), or phase-reversal amplitude shift keying (PR-ASK) using a pulse-interval encoding (PIE) format. Tags receive their operating energy from this same modulated RF carrier"

I'm looking for the maximum allowable baud rate deviation for the BLUENRG-232.In the data sheet I find no information about it. Maybe someone knows the specification or where I can find it.

I can not find the LCD connection parameters for STM32F769I-DISCO.RD, RS, RST, WR, BLED, CS, in the program mikroPascal Pro for ARM.The screenshot shows what the parameters are.
