Posted on February 09, 2018 at 15:05Hi all,I would like to integrate the SPBTLE-1S bluetooth module in a new own PCB design. I want to connect the bluetooth module with a STM32F215 MCU through I2C interface.I have performed the schematic following t...
Posted on June 07, 2018 at 09:21Hi,I'm using a SPWF04SA wifi module.When I create a file (for example sample.json) with AT+S.FSC command the module saves that file in its ram memory.How can I save that file in the internal or external flash memory ?...
Posted on January 31, 2018 at 13:59Hello,I'm trying create a script in uPython in order to get control of the wifi module SPWF04SA/SC. I have successfully updated FW and FS via UART and right now I'm using RELP via UART to test out some code. Can so...
Posted on June 05, 2018 at 13:35Hi everyone!Is there an antenna design inside SPBTLE-1S?Or do I have to do my own artwork?Thanks in advance.Bests regards!
Posted on June 01, 2018 at 19:08Hi, During a stress test of sprit1, using the module SPSGRF 868Mhz, I've noticed an undocumented MC_STATE with value 0x41, some one know the meaning of this state ?The module is in RX mode receiving continuously mes...
Posted on May 11, 2018 at 12:33Hi,In my device I use BlueNRG-2 working as Network Processor (DTM firmware is loaded there).It cooperates with STM32 where is my application. Processors communicates each other via SPI interface.It works fine for long ...
Posted on May 31, 2018 at 09:47Hi,What is the purpose of usage the inductors (L1, L2 marked below) in parts of the circuit responsible for clock?What values should have these inductors?Regards,Piotr RomaniukPSBelow is an application circuit from the...
Posted on May 28, 2018 at 11:13Hello everyone,I've got one question about SPWF04 usage.Hardware design: There is SPWF04There is SD card connected to SPWF04There is a host MCU that controls SPWF04 over SPIWhat it has to do: Host MCU collects data f...
Posted on May 28, 2018 at 12:58I want to access LSM6DS3 sensor which is present on STEVAL-IDB00BV2 board, using direct register methodology (no interrupt )I tried to initialize SPI as follow. Am I on right track ?void spi_init(){ CKGEN_SOC->CLO...
Posted on May 26, 2018 at 11:37Hi,I am using BlueNRG-2 chip with DTM firmware. It is connected to host processor STM32 by SPI.This bluetooth device works in peripheral role (some sensor).Advertisement works fine: another device that is a master rece...
