Posted on October 21, 2017 at 17:34Hello Everyone,I'm struggling to setup communications between two 868 MHz sub-GHz modules.The first module is the STEVAL-IDS001V4M (USB dongle with SPSGRF-868) and the second module is the STEVAL-SP1ML868 (USB dongle with SP1ML-868). I'm using the Windows application 'SPIRIT1 DK Application v2.2.1' to configure the radio and packet settings of the STEVAL-IDS001V4M module, then using the 'Transmission Test' window to send the text 'Hello World'.The radio and packet settings for the STEVAL-IDS001V4M are as follows (configured via the GUI):Frequency Base: 867.999967 MHzData Rate: 38.433 kbpsFrequency Deviation: 19.836 kHzChannel Filter: 102.115 kHzModulation: 2-FSKOutput Power: 0 dBmPacket Format: BASICPreamble Length: 4Sync Length: 4Sync Value: 0x88888888CRC: No CRCFEC: DisabledData Whitening: EnabledThe radio and packet settings for the STEVAL-SP1ML868 are as follows:S00:BAUD_RATE=115200S01:FREQUENCY=868000000S02:DATA_RATE=38400S03:MODULATION=0S04:OUT

Posted on October 20, 2017 at 20:53I have a project in which we are making a small IoT device. It will be using Wifi using the http://www.st.com/content/st_com/en/products/wireless-connectivity/wi-fi/spwf04sa.html. We would like to just add low priority tasks to the code inside the http://www.st.com/content/st_com/en/products/wireless-connectivity/wi-fi/spwf04sa.html which would require that we get the source code for it. Has anyone hear of people doing this?

Posted on October 19, 2017 at 15:03Hello! I cant close socket client be command AT+S.SOCKC -  “ERROR: Pending dataâ€� is raised'.  According to UM1695 it should be flushing pending data  (using the AT+S.READ command) is mandatory before closing the socket connection (AT+S.SOCKC). If the buffer is not erased, the “ERROR: Pending dataâ€� is raised. . I cant find description AT+S.READ. How can I do that properly?AT+S.READERROR: Command not foundAT+S.SOCKC=00ERROR: Pending data

Posted on October 18, 2017 at 10:58Hello,I'm pretty new to BLE devices. I intend to develop a BLE central application device that needs to run in low power most of the time. This central device will be paired with some other slave devices arround. My slaves will send data when it is needed. My question is the following and regards the central application device : is it possible to combine a BLE central application device and ultra low power, that is to say, is it possible to wake up my device when there is data to listen ? Or do i need to manually set my device in RX mode and wait for data coming from my slaves ?If you have any ideas, don't hesitate to share your thoughts :)Regards,Aurélien

Posted on March 15, 2017 at 10:48Hi,What is the best way to generate custom BLE 128 bit UUIDs ?How has ST generated the custom UUIDs in the firmware examples of Sensortile kit related to BLE ? For example, following are some UUIDs(in bold) in one of the firmware example :/* Hardware Characteristics Service */&sharpdefine COPY_HW_SENS_W2ST_SERVICE_UUID(uuid_struct)    COPY_UUID_128(uuid_struct,0x00,0x00,0x00,0x00,0x00,0x01,0x11,0xe1,0x9a,0xb4,0x00,0x02,0xa5,0xd5,0xc5,0x1b)&sharpdefine COPY_ENVIRONMENTAL_W2ST_CHAR_UUID(uuid_struct) COPY_UUID_128(uuid_struct,0x00,0x00,0x00,0x00,0x00,0x01,0x11,0xe1,0xac,0x36,0x00,0x02,0xa5,0xd5,0xc5,0x1b)Is there a tool available for the same ?Best Regards.#ble-128-bit-custom-uuid #uuid #bluenrg #st-bluenrg

Posted on October 17, 2017 at 10:05I have an STEVAL-IDS001V5M dongle I'm trying to test.  I installed the SPIRIT1 DK v. 2.2.1 on my Windows 10 PC.  During the install one of the driver installations fails (the usbser device installed by dpinst_amd64.exe), but my dongle still comes up as a COM port.  Two other device drivers are installing correctly, and I've tried multiple re-installs of the first driver but it always fails.Despite the failure I can connect to my dongle via Putty and talk to it ok.  When I run the SPIRIT1 DK GUI it finds the COM port for the dongle (COM27 in my case) and when I open it I get 'Old GUI Firmware detected.  Now a firmware update procedure will be started...'.  When I click OK I get a warning about making sure the orange LED is flashing and the COM port disappears from the device manager (I guess the board is being put into DFU mode).  The orange LED is flashing so I click Apply but then, after about 10 seconds, I get a '

Posted on October 05, 2017 at 10:47I am evaluating the use of the SPBTLE-1S module, based on BlueNRG-1 and Bluetooth v4.2 compilant, to interact with iOS. BLE 4.2 specification includes data length extension feature which improves throughput and reduces transaction time. However, according to documentation, only BlueNRG-2 supports BLE extended packet length feature. Is it possible to upgrade BLE stack embedded software (library managing the RF part) with a version wich extends the possible MTU size up to 158 bytes?Thank in advance.

Posted on October 09, 2017 at 11:42Hello All, i want to modify the application on the Details Activity class. I want there to change the temperature into weight because i would like to make some messurements with some resistive wire strains. So did anyone changed something in this folder?#bluenrg

Posted on October 06, 2017 at 15:49Hello,   I'm working on a project, where I need RF transceivers. I chose Your SP1ML transceiver modules, but I was dissapointed when I tried the devices, because the low distance range. The distance range abaout 20-23 m. Above this distance the devices didn't communicate with each other. I didn't find documentation anywhere, about distance range, or about register settings of this module which I can achieve the best performance.Can You help me? Anybody tried this transceivers? What is the best distance which You can achieve?Sincerelly,Szabolcs Vass#spirit1-sp1ml #distance #range

Posted on October 04, 2017 at 14:34Hi,I have recently just started working on Wi-Fi code on the SPWF01SA module using the STM32F1 Nucleo Development Board.I was able to get the various configuration values from the Wi-Fi module using the functions below. And I displayed these values in HyperTerminal as can be seen below:Is it possible to change the IP address of the module from the default value (192.168.0.58) to another IP address?If it is possible, can someone explain to me how it is done?Thank You,Ernest#wifi-module #wifi-usart #stm32f1-nucleo #idw001v1 #spwf01sa1 #wifi-spwf01sa

Posted on October 02, 2017 at 04:56Hi,I tried to add OTA function in BLE_SigFox_SensorDemo project,and according to OTA guide, I have to add, ST_OTA_LOWER_APPLICATION=1 or ST_OTA_HIGHER_APPLICATION=1 as preprocessor and linker options.After adding ST_OTA_HIGHER_APPLICATION=1 in linker options,IAR shows error message LP011, which represents setion placement failed.Can someone help me here? Thanks.

Posted on September 28, 2017 at 09:49Hello. I have got a few questions about  BLUENRG-MSCSP. Could you help me? 1. What par of an inductor you recommend ( Power management strategy using step-down DC-DC converter )? What par of a capacitor  you recommend for filter of tep-down DC-DC converter for  better stability?  I will benefit in energy consumption by  step-down DC-DC converter  in  practice? 2 I base  my design on the board  STEVAL-STLCS02V1. On this PCB there are many different  par of a capacitorts. I want to replace 100nF ->150nF, 1uF-> 2,2uF  for part optimisation. Doesn't  action  influence for stability or other things? 3  On the board  STEVAL-STLCS02V1 the circuit 'TEST1' goes to the  microcontroller STM32F476.  What is a signal TEST1? Can I pull-down to GND TEST1 ?  4   BLUENRG-MSCSP has  got   the Low speed ring oscillator (LSROSC) . If  I don't use  

Posted on September 27, 2017 at 15:57In my program i'm doing FOTA via BLE.I developed my code with Nucleo-l476RG EVB and Nucleo-IDB05A1, based on the FP-SNS-FLIGHT1 program.Now I'm working with my custom PCB using STM32L476JEY as MCU and BlueNRG-MS and have problem with system reset.I can see all the packets transferred successfully with correct CRC. I write the firmware to address 0x08040008 and add the magic number to 0x08040000. Then, when resetting with HAL_NVIC_SystemReset() function the old program is restarted.The __ICFEDIT_intvec_start__  address was: 0x08000000, so I supposed that my program takes the bootloader place and Ichanged it to 0x08004000, also the VECT_TAB_OFFSET to 0x4000.With these changes  the reset doesn't work in any case, even before doing OTA via BLE. I can just flash my program from IAR.I'll be happy with any ideas ,thanks#fota #stm32l476 #bluenrg #system-reset
