BLUENRG-M2SP schematic
I need the BLUENRG-M2SP schematic to qualify the application with the STmicro electronics library. I need to configure the mode of the AC/DC converter. The spec sheet is not documented enough. With the schematics, I will understand what I need.
what is the use of SPI_IRQ pin in IDB05A1 BLE module.

How to read phase angle difference between voltage and current using stm32f407?
Hello All,I have recently started using STM32 mcu and quite new to it. I am developing a project in which 3-phase energy meter is needed which measures voltage, current and power of 3-phase AC signal for which MCP3903 IC is used, as I came to know th...

How to make Bluetooth work when using a STM32F401RE board and a X- NUCLEO- IDB05A1 extension board ?
Hello, I'm a student engineer and I'm working on a project which aim is to retrieve environmental data such as Temperature, Humidity and luminosity... and to send them via Bluetooth to my phone. I'm using STM32F401RE board + X- NUCLEO- IDB05A1 and co...
Battery Lifetime in BlueNRG current consumption estimation tool
Which is the state between two advertising events for the calculation of the battery lifetime?Shutdown or Deepstop?Is the current profile shown in the plot obtained when exiting shutdown or deepstop state?Thanks
Unable to debug or program steval-IDB008V1M using ST-LinkV3.
https://community.st.com/s/question/0D53W00000TFnQJSA1/unable-to-debug-or-program-stevalidb008v1m-using-stlinkv2The question in the link above is exactly similar to mine, but instead I am using a ST-LinkV3 debugger instead of their V2. I figured I wo...
