Posted on April 16, 2018 at 15:31Hello!I am searching for the simple way of pairing on BlueNRG-1 by pressing a button on device.We have a device, which has no keyboard and display, only some buttons. We want to enable/confirm pairing on this device by pressing a button. We also need to bond this device to smartphone for communication.What pairing mode can you advice to use on this device?'Numeric comparison' mode, which I have tried, works on Android 6 and above. I can press button to confirm the code which is shown on the phone and is the same on the device.But on Android 5.1 (and earlier) phone always asking to enter the code in numeric comparison mode. And because we can't show the code, which user should enter on the smartphone - this is the issue.I have tried the 'JustWorks' pairing mode, waiting for pressing the button on device, before entering the function:aci_gap_slave_security_req(connection_handle); - but seems it's not working as I need.The first connection really waits fo

Posted on April 04, 2016 at 10:15Good morning to all,  I have a little problem with my module. After a filesystem update I send the command AT+CFUN=1 to reset the module. The module return OK, return ''+WIND:2:Reset'' but don't resect. Why?Stefano #spwf01sa #bug

This converter is used to communicate an Android mobile phone application with an automation controller. The Android application emulates a serial terminal, behaving like an old Televideo 905 device.So the automation controller is continuosly sending streams of serial data for presenting it on the terminal, i.e. It is continuosly refreshing a display.The problem I have is that the SPBT3.0DP2 module seems to buffer the data in big chunks before sending it via the BT radio, causing all kinds of display refreshing problems in the Android application, as some effects like blinking are achieved by alternating visualization fields between blank and not blank characters.This problem doesn't happen when connecting through an AMBER module, as it seems to not buffer so much data bef

Posted on April 20, 2018 at 09:00 Hi there, I'm working on STM32F103 and a WiFi module SPWF01SA. I used the ST middleware and I can communicate with the WiFi module only without the Hardware Flow control. I configured the USART1 with Flow Control using Cube32Mx huart1.Instance = USART1; huart1.Init.BaudRate = 115200; huart1.Init.WordLength = UART_WORDLENGTH_8B; huart1.Init.StopBits = UART_STOPBITS_1; huart1.Init.Parity = UART_PARITY_NONE; huart1.Init.Mode = UART_MODE_TX_RX; huart1.Init.HwFlowCtl = UART_HWCONTROL_RTS; huart1.Init.OverSampling = UART_OVERSAMPLING_16;�?�?�?�?�?�?�?�? I copied this configuration from the example project. In fact this project use onlt the RTS pin. I connected the WiFi CTS pin to the MCU RTS pin. and the WiFi RTS is unconnected. The WiFi initialization works well until I send the command status = SET_Configuration_Value(CONSOLE1_HWFC, 1); After this command the WiFi module does not respond anymore. Any suggestion? Thanks for th

Posted on September 27, 2017 at 09:26I am developing a project using SPWF01SA module. I have successfully configured it and used it. But I want to use Hardware Flow control, how do I enable it? I searched datasheet and user manual but didn't found any information on this. #wifi-spwf01sa

Posted on April 19, 2018 at 11:10Hi All,We are looking for a Chip Antenna for S2-LPQTR. We need 433MHz RX with a 100-200m range requirement. We are using S2-LPQTR since it drains only a low current and it has only a small form factor. We need a chip antenna which can be used for this application. I am looking for chip antenna since we have space constraint reason. We don't have any expertize in antenna designing. So we need your suggestions & recommendations for designing the 433MHz RX with S2-LP. Please provide reference schematics of S2-LP with the chip antenna if there is any.Any help will be greatly appreciated. Thanks in Advance.Best Regards,Krishnaprabha S Naik#s2-lp #s2-lpqtr

Posted on April 17, 2018 at 16:53Hello,I have a STEVAL-FKI868V1 based on a Nucleo L152RE board and i would like to connect a RS232 to my RX pin to get the information and then send it when i click on the button.So my main problem is about the code to developp to get the information from the RX.Is someone could help me, please.Thx

Posted on April 10, 2018 at 14:28Hi. I read that it is possible to stream audio using BT 5.0 interfaces, from one to many devices. For example in a home application where I use my smartphon to play sincronized high quality audio in all the rooms. Do you confirm it? Is there an application note about this application? Does it work also in mesh mode?

Posted on May 02, 2017 at 19:16I am attempting to use the SPI interface of the SPWF04S module but with very limited successI can get the module out of RESET with the SPI interface enabled by simply pulling the interrupt pin high as the reset pulse ends. The module sends some WIND messages that all make perfect sense. I get 'console active' 'wifi hardware started' etc etc and eventually it settles down to doing scans every few seconds ( I get 'scan active' followed by 'scan complete' repeatedly) That's all good.I can't get the module to respond to any commands I send it. Lets say I want to send the simplest command (AT) just to determine if the console is alive... Here is what I've tried so far1- SET CS low ... Send 0x02, 0x00, 0x02, 0x01, 0x00 ... Set CS high ... Wait for INT to go low ... Read response2- SET CS low ... Send 0x02, 0x00, 0x02, 0x01, 0x00 ... Leave CS low ... Wait for INT to go low ... Read response3- SET CS low ... Send 0x02, 0x00, 0x02, 0x01, 0x00 ... contin

Posted on March 22, 2018 at 21:59 Hi. I have downloaded theSTM32CubeExpansion_BLE1_V3.2.0 folder from the STM website and am trying to compile the demo project. I am using Keil V5. I have copied the files over to where all my other Keil projects are and have included the relative header paths. When I build it I get over 200 errors. I'm sure the code is fine and it maybe something to do with folder locations or something like that. Is there any special procedure for copying projects and where to copy them to? Thanks. #keil #bluenrg-2 #stm32f407 Note: this post was migrated and contained many threaded conversations, some content may be missing.

Posted on April 10, 2018 at 08:59Hi, I want to use M41T62 calendar and sqw output functions in the same time. I try the below code, after call bsp_m41t62_set_sqw(sqwValue); the time in calendar stops and no more increment. But if I read all the register every time, the calendar start increment, but it take more power and time, so this action is not allowed.My question is how to use SQW and calendar function in the same time? and why the SQW will effect the calendar function?// --------------------------------------------------    bsp_m41t62_set_rtc_time(18,12,13,1,20,30,30);    bsp_m41t62_restart();    while(1) {        bsp_m41t62_get_rtc_time(&rtcTime);        /*        bsp_m41t62_read_all(rtcRegVal,16); // if run this code,the calendar start increment        uart2_tx(rtcRegVal,16);  &nbs

Posted on April 04, 2018 at 15:30Hello, I am currently developing a BLE product using BlueNRG2. I see in the datasheet that it is Bluetooth v5 compliant, but in the sample codes for STEVAL-IDB008V1, the APIs do not support Bluetooth v5 features such as extended advertisement. Are there any existing BlueNRG2 APIs for Bluetooth v5 features?

Posted on December 20, 2017 at 10:37 hi. im running a provided example of HID periphProfiles. using STEVAL-IDB005V1D on NXP platform (FRDM-KL43) SPI lines are OK, i can read header from the blueNRG-MS. the thing is IRQ always high. so that at the moment i configure the IRQ at NXP, interrupt occurs and making NXP always tries to receive data from BlueNRG. i've tested the original example earlier on nucleo platform, and it was working fine, but haven't checked the specific state of the IRQ. Is it suppose to work this way? have i broken something in the porting process? #bluenrg-ms #irq-bluenrg-ms Note: this post was migrated and contained many threaded conversations, some content may be missing.

Posted on April 04, 2018 at 07:02Hi,First of all, sorry for the lengthy message.We are developing a 433 MHz transceiver using SPIRIT1. We were able to run 'SDK_BasicGenreic_A' program provided with the development kit on 'STEVAL-IKR002V3D' daughter-board. But, when we are trying to dump the same code in our own board, SPIRIT1 is unable to enter into 'LOCK' state. We have ensured that the following conditions are met:1) SPI communication is working (able to read and write to SPIRIT1 registers)2) 50 MHz sinusoidal signal got generated at crystal's terminals (observed using DSO)3) SPIRIT1 is entering into 'STANDBY' and 'READY' modes (checked MC_STATE1_BASE register status)We have compared all the register values at various stages of the code with those of the reference board's registers. All of them are exactly the same, except for '0xB2', which should have been changed to 0xCA, but still is 0x42 (default value).The major difference is occurring, when we exe
