Posted on February 13, 2018 at 14:49Hi,I have a question about the STEVAL-FKI868V1 development kit that is based on the S2-LP sub 1GHz transceiver. We have a system that works at 868MHz and the signal that commes from the system is fed into multiple...
Posted on August 04, 2016 at 09:33Hi, The description in the .h file states that: '' * @param en_high_power Can be only 0 or 1. Set high power bit on or off. It is strongly adviced to use the * right value, depending on the...
Posted on May 12, 2018 at 06:46Hi,I am able to communicate with BlueNRG-2 either by ST-Link Utility or by Atollic GDB. Unfortunatelly, when I start regular work of DTM firmware, these tools lose communication.What is the reason of that?Is it caused ...
Posted on May 11, 2018 at 07:37Is it possible to use BlurNRG BLE stack in STM32F103 CPU and use UART as a HCI interface to any Bluetooth chip?Read through BlueNRG manuals and those looks like BlueNRG is ment to be used only in SoC and ACI layer betw...
Posted on May 13, 2018 at 09:42Hi,I am confused by documentation of BlueNRG and various description of exiting from WFI for Cortex-M0.What is going on when BlueNRG-2 is woken up from deep sleep by external gpio pin?Is the program continuing executio...
Posted on May 12, 2018 at 19:10Hi All,I'm evaluating the the S2-LP transceiver at 868 MHz using the Nucleo expansion board and the S2-LP DK software.I need a clarification about the automatic frequency correction: as far as I understood from the dat...
Posted on May 12, 2018 at 10:29Hey,the SPWF01 module automatic writes the received data from a tcp socket client. Is there a way to have this in the SPWF04 module?If not, how can I read the data?Module Output ...
Posted on May 03, 2018 at 17:14Hi, i am an embedded electronic engineer and lately i have a project named 'plug meter' based on an STM32 MCU and the STPM01 AFE, but i couldn't establish the SPI communication between AFE and MCU because there are no ...
Posted on April 18, 2018 at 16:32Hi,I cannot build working DTM for BlueNRG-1 on TrueSTUDIO (9.0.0).When I program the device with prebuilt DTM_SPI.hex from Firmware folder in ST Development Kit it works fine. STM32 connects with BlueNRG, configures ...
Posted on September 28, 2017 at 04:06Hello,I was planning to use the SPWF04S module in a product where all the processing is done in the stm32F439 embedded in the module. It seems like the only way to load an application code is to go through the uP...
