Posted on November 14, 2017 at 23:51 Hi I am trying to debug with the IDB007V1 dvelopment board and a STLINK V2 but the debug process fails at the FLASH download. I have tried the sensor and hello world demonstration programs with the same res...
Posted on June 11, 2018 at 16:03On the application I'm developing on a NUCLEO-IDW04A1 (which as the SPWF04SA module) I have consistently run into issues where I cannot interface correctly with other hardware because the version of micropython on the...
Posted on November 03, 2015 at 16:29Hello,I'd like to have some clarifcations regarding BLUENRG-MS capacities to handle multiple simultaneous connection as a Master and Slave device.From what I undertand, the chip have to configured with Stack Mode...
Posted on May 23, 2018 at 15:55Hi!I am working in a project and we need to use one BLE chip.I found the chips from ST (BlueNRG1-2) but I can't find good information about:- Can these chips be used as principal MCU and like BLE device at the same tim...
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 ...
