Interface and connectivity ICs

Posted on April 04, 2016 at 10:58When I load a webpage from  this module with some images (not so big and non so many) the module became slow and often kill the connection (timeout). I suppose this behavior came from the limited amount of RAM, as evinced even in other posts, but maybe someone have a suggestion for a better result.Otherwise, in my opinion, the internal webserver is useful only for config purpouse and demonstrations...Stefano

Posted on April 04, 2016 at 09:50Dear Madam, Sir,Would You inform me about the type of crystal what SPSGRF board uses.I have developed and manufactured 250pcs Spirit1 boards with this crystals.http://www.ndk.com/images/products/catalog/c_NX3225GA-STD-CRG-1_e.pdfAll my boards with my radio able to communicate to each other using FC_OFFSET1 = 0 and FC_OFFSET0 = 0 value. But those boards which area mounted the buyed SPGRS can't communicate with my radios. I know a can tune syntesizer of SPSGRF boards to my requirement.Can You garantee that the your SPSGRF boards will mounted the same crystal in the future? Need I check all buyed SPGRS modul crystal tolerance during manufacturing process all the time in all modul?Thank Your answare in advance  Laszlops.My radio params are#define XTAL_OFFSET_PPM             0 #define CHANNEL_SPACE                250000#define MODULATION_SELECT       &nb

Posted on March 30, 2016 at 22:45Hi, Is there any way of assigning a unique ID to a &sharpinput tag in html, so that when I get the WIND:56: message prompting for data input, I dont have to worry about figuring out which page has been served? At the moment I just get the index as expected, 1, 2, 3 etc, so my only idea is to write a state machine and use output.cgi to output the name of the page being navigated to, to set the state, so then I know *which* data index 1, 2, 3 are actually requesting. :( This seems really laborious, and would mean that browser back and forward buttons wouldn't work unless there is a way of calling output.cgi on a page load... I have the shtml structure working, but it seems like knowing which page+index is being requested would be a very common requirement so wanted to ask before re-inventing the wheel. Can anyone point me at the CGI&SSI Application Note that I have seen mentioned in other threads? I dont seem to be able to find it anywhere and I

Posted on March 31, 2016 at 00:04I just fired up the SPWF01S module on a prototype board that I made.  Got WIND:1, WIND:13, WIND:3, WIND:0, then this error over and over. I didn't send anything to the module.  Did I forget to connect something, is the module requiring setup, or is the module damaged? Thanks #initial-spi-read-failed

Posted on March 30, 2016 at 10:48Good morning,  I have some problems regarding firmware update. When  I try to update firmware via serial link, I obtain this message:''Error sending message 0x31 to device'' as show also in the image: Someone can help me?Stefano

Posted on March 30, 2016 at 12:47Hello, I am using SPBTLE-RF BLE Module along with X-CUBE-BLE1 sensor demo code. The program worked successfully when run on STM32L053 Nucleo board with SPBTLR-RF module. But when we ran the X-CUBE-BLE1 code on our PCB (Which is designed based on STM32L053 Nucleo board), the microcontroller resets just after setting SPBTLR-RF  in discoverable mode. Using the following API:aci_gap_set_discoverable(ADV_IND, 0, 0, PUBLIC_ADDR, NO_WHITE_LIST_USE,sizeof(local_name), local_name, 0, NULL, 0, 0);    It seems that the SPBTLR-RF sending a few advertising packets for few milliseconds just before the microcontroller resets. #ble #bluenrg-ms #spbtle-rf-ble

Posted on March 28, 2016 at 21:47Hi everyone, im using a STM32F0 Discovery Board to connect a Waveshare WIFI Modul and need some example code or some tutorials how to connect WIFI and to send/receive data & AT Commands using UART. Unfortunately i cant find it. can someone help me ? Thanks

Posted on March 16, 2016 at 10:37Hi, In our product prototype we are using SPBTLE-RF BLE Module (BlueNRG-MS) for BLE connectivity. Due to space constrains in our product we are not using the EEPROM chip as given in the evaluation board X-NUCLEO-IDB05A1 of SPBTLE-RF. -> Is it possible to use SPBTLE-RF module as standalone (Directly connected to SPI port of microcontroller) with our using EEPROM? -> Did anybody have example codes for SPBTLE-RF BLE Module (Note for X-NUCLEO-IDB05A1)? Best Regards Salman Khaja #bluenrg-ms-x-nucleo-idb05a1 #spbtle-rf #bluenrg-ms #ble

Posted on March 14, 2016 at 07:48We're using the STM32Nucleo + BlueNRg Expansion HRM profile with Android smartphone as a master.  The connection interval is ~ 50 ms as dictated my the master. We would like to get access to the Android app''STM32 BLE ToolBox'' source code. The intent is to adjust the connection interval from the default 50 ms to 1 to 2 seconds. Is it possible to get a link where we can download the source code from? Any other suggestions to increase the connection interval are welcome. Thanks, -JP #ble-connection-interval

Posted on March 22, 2016 at 09:14Hi. Sorry for my poor English. My bluenrg device is not present in list of bluetooth devices in iOS settings, but iOS can connect to bluenrg with LightBlue and any other application. How can I add my bluenrg to list of visible devices? *I haven't such issue with android. I'm using SensorDemo.bin for STM32L053R8-Nucleo board form STM32CubeExpansion_BLE1_V2.5.2. iOS version 9.2.1

Posted on March 21, 2016 at 14:27I'm working with the BlueNRG in a system that has 4 services.  I'll go into a bit more detail:Service 1 has 4 characteristics : 1 - RW 20 bytes (reduced to 17, see below).2 - RN 20 bytes3 - RW 20 bytes4 - RN 8 bytesService 2 has 3 characteristics:1 - W 2 bytes2 - RN 8 bytes3 - W 8 bytesService 3 has 5 characteristics:1 - RW 20 bytes2 - RN 20 bytes3 - RN 20 bytes4 - RN 20 bytes5 - RN 20 bytesand finally, service 4 has 2 characteristics:1 - RW 8 bytes2 - RN 6 bytesMy problem is that, in the above configuration, the call to aci_gatt_add_char for the last characteristic fails with ERR_UNSPECIFIED_ERROR with the values as shown above.  However, if I reduce the first characteristic of service 1 from 20 to 17 (by removing three ''reserved for future use'' bytes from it), then everything is fine.The error began to occur when one of the other characteristics grew from 18 to 20 bytes (don't recall which one).  Th

Posted on March 21, 2016 at 14:06I'm not sure if this is the place to ask this (it may be a generic bluetooth question, I'm a bit of a newbie at this), but please bear with me.I had a bug in my software where I had accidentally declared in ACI_Gatt_Add_Characteristic a characteristic with a variable length value field (it isn't, it's fixed length).  It contained a 20 byte structure.  When calling ACI_Gatt_Update_Char_Value, I tried updating only parts of the structure by using the offset and length parameters.  This changed the size of the characteristics value each time.I modified the length to be fixed length, but because I re-read the documentation, also modified the calls to the function Aci_Gatt_Update_Char_Value to always having offset 0 and length 20, because I don't understand what this means (from the documentation):Val_Offset:The offset from which the attribute value has to be updated. Ifthis is set to 0, and the attribute value is of variable length, thenthe

Posted on March 16, 2016 at 09:38Hello everyone. Software: X-CUBE-BLE1 (v. 2.5.2) http://www2.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-expansion-software/x-cube-ble1.html Example: Sensor Demo Application with DMA and low power mode (Project Name: DMA_LP_SDemo) 1) Equipment: NUCLEO-L053R8 + X-NUCLEO-IDB04A1 - Current consumption in operation mode advertising: about 15 �A - Current consumption in operation mode connections: about 130 �A 2) Equipment: NUCLEO-L053R8 + X-NUCLEO-IDB05A1 - Current consumption in operation mode advertising: about 300 �A !!! - Current consumption in operation mode connections: about 130 �A Power supply voltage 3.3 V.

Posted on March 09, 2016 at 16:07Hello! We use SPWF01SA module for Internet access to our device. We are using this script - input.cgi - to channel data from STM32F439 to web application (web server). Client gets data using Ajax which use input.cgi. It works fine... for 2-5 minutes, then it stuck  - firstly module send ''timeout occured'': +WIND:56:Insert message to client: TIMEOUT OCCURRED!  then it stops send anything, sometimes exact in the middle of phrase, for example: +WIND:56:Insert message to And then radio dropped wifi connection. Looks like module locks up. Data that module gets from STM32 is 107 bytes long. Why does module stuck? Is it too long - 107 bytes - for this script? I can post html side here if it helps.

Posted on January 02, 2016 at 17:03I'd like to read IFR registers of my BlueNRG-MS module. Using BlueNRG GUI I can read chips' version, I can initialize it and I can update the firmware. But I can't read IFR. When I go to Tools... -> BlueNRG IFR... and click Read I get: ParsingError Unknown vendor code What can be the cause? #bluenrg-gui-ifr

Posted on February 19, 2016 at 08:52Hi, your BlueNRG-MS examples look very powerful - supporting Chat? So I would assume that it is possible to get a datarate in the range 20kHz * 16 Bit, so about 40kByte/sec or 300kBit/sec - is this true? Does this work only from BlueNRG to BlueNRG, or does this work also, if I connect the BlueNRG-MS to an Android smartphone, e. g. Samsung Galaxy 5/6? Is there some simple Android example code (best in Java) to show/test this chat functionality? Could this also be applied to transfer of smaller/medium sized files (up to e. g. 100kByte)? Does the BlueNRG DK sample code contain any ''hidden code'' / Lib inclusion, or is this complete c code (unfortunately this shows only IAR-EWARM projects, but I work with Keil-ARM-MDK). Is there anywhere some info, how to setup the projects in another IDE (at least a list showing the source files necessary for each project?).

Posted on August 06, 2015 at 00:02Reading and writing the SPIRIT1 radio registers directly, doesn't seem to work.Here is one simple example...AT/SR36=10OKAT/SR36?36=88AT/V reports SP1ML-915 HW:V1 FW:V0.12Is there a more recent firmware version that addresses this?
