Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
We have an application where the STUSB4500 is used in conjunction with and STM32L4 family MCU, handling USB2.0 data. So the STUSB provides power (USBPD) and the DP DM lines are routed to the MCU. There is an issue specifically when using a macOS lapt...
Hi! I'm working with spirit1 module. I'm monitoring internal registers reading them one time per second. After reset mc_state registers C0 and C1 contains values 0x02 and 0x07, what means READY state. I'm trying to put it now in RX mode with command ...
Hello,Is they have any PCB antenna design (.dxf file or other) which i can use with BlueNRG-2N ?Tahnk you,Sincerely.
I want to connect 7 LED's on one output in series, using a current of 20 mA. Each LED can have a forward voltage of 3V, which means 7 x 3 = 21 V. I want to use a power supply of 24V.I read in the specifications that the max Vo (Output Voltage) is rat...
Hello,anybody can explain to me the difference between the BlueNRG-2 SoC and the BlueNRG-2N co-processor?Thank you,Sincerely
Hello, I'm using git with my project based on a CubeWL example. After wanting to add this gitignore and delete unnecessary files (i.e. examples that I don't use, but I kept the drivers of course), it doesn't work anymore... ...Git/STM32WL55/STM32Cube...
We are trying to integrate the STEVAL-STMODLTE chip into the NRF52 for rapid prototyping.Trying to interface nrf52840 with the STEVAL-STMODLTE chip via UART. Connecting the RX and TX, and sending the "AT" command after the UART initializes, the modem...
Hi all,We have solution based in a STM32G0B1 microcontroller which needs a very fast communication towards an SPI memory, for doing that, we think in using the dual spi read mode (DREAD), is possible to that whithin this micro? Or we have to go to an...
Hi,I am trying to use a custom OTA application to perform firmware updates. The code works (default Service manger OTA code from the DK) till the image size of the app uploaded is below the address 0x10057800. As soon as the firmware image exceeds th...
So I am trying to use BlueNRG-MS, SPBTLE-RF device on a custom board. To use this device i tried to use BLE cube expansion with SampleApp application. I am configuring SPI and GPIO pins correctly. Project builds and loads fine but after booting but c...
