Hi,I'm having problems to activate the built-in BlueNRG-2N bootloader. I put DIO7 high (Boot) and perform a reset (/Reset 5ms low then high again).Then I wait 150ms to give the bootloader a little time to initialize. Then I send 0x7F on the UART-line...
I'm looking for UWB solutions compatible with Apple's U1 chip ecosystem.Does or will ST have anything like that?I only found B-UWB-MOD1 in proposal, and it operates in a different Frequency range.
Hello everyone,I've been working on a custom board that incorporates the STUSB4500QTR. My aim was to set it up using the Nucleo-F072RB and STSW-STUSB002. However, I'm facing an issue where the Power Delivery Objects (PDO) configuration screen won't d...
Hi,I'm asking the bootloader of an BlueNRG-2N for the "Get ID" command and it responds 0x02 0x01 0x4F.The upper nibble of the last byte ist 4. But 4 is not mentioned in AN4872.4 means ???2 means BlueNRG-20 means BlueNRG-1Any hints?Regards.
I am using the BlueNRG2 in an application which is a simple button press to indicate if it is pressed or not. The device needs to connect to Windows 10 and or 11. I am using the SensorDemo project as the base code and made a few changes to just utili...
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 ...
