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 ...
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.
