Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
I have problems to write to flash memory at address 0x10040000 via UART bootloader on BlueNRG-2.Flash start is 0x10040000, but I can only flash the memory from 0x10042000 on, which is a 8kB offset !?The memory is successfully erased before.Second que...
I want to programatically modify the PDO profiles on the fly depending on the available power. The document stusb4710.pdf implies that this is possible:"The STUSB4710 has a set of user-defined parameters that can be customized by NVM re-programming a...
We are looking to add a pre qualified bluetooth module to a consumer product and the device live outdoors and periodically connect to a phone. We have identified the BlueNRG-1 as a candidate but perhaps there is a better choice. How well is the BlueN...
I have a BlueNRG-M2SP on a board with an STM32 Host. I assert the boot pin high and reset the M0 at the start to put it into Bootloader mode. I wait for the popup and set the baudrate, so far so good. When I issue a command with the Flasher Utility i...
Hello everyone,I've been trying to load profiles that are not from Truphone onto the ST4SIM, but all I get are errors. The most basic question I cannot find an answer to is whether the chip does not allow loading profiles from external companies.I'm ...
Currently, I have two STEVAL-IDB011V2 boards (as shown in the figure). One is to send the signal as a transmitter, and the other one is the receiver. After the channel (between Tx and Rx) modulates the signal, how can I extract the carrier signal wit...
Hello,During testing with the STUSB1602, I encountered strange behavior when using the DRP-mode. Connecting a USB power bank in this mode does not result in a successful connection. Only after pressing the engage-button on a Powerbank, the connection...
Is it required to put external TVS diodes along with the ST4485EB RS485 IC on the A and B lines? I see the datasheet and notice that there is in-built ESD protection as shown in the data sheet snapshot below. Please advise.
Hello together,is there any part marking decoder for STM devices ? like Micron Technology or TI have.Best RegardsPatrick
I have some following up questions after my last post: https://community.st.com/t5/stm32-mcus-products/lsm303dlhc-c/m-p/597950#M224881. I now have a code that does not give any errors. with the librarys in the picture below. But when i run the code a...
