Resolved! How to get LTK

Hello community, I am currently considering capturing and analyzing BLE packets by using BLE sniffer, but for that I need the LTK used for decryption.BLE Secure Connection pairing does not directly exchange LTK, so I do not know where to find it exac...

STM32WL5MOC LoRa Range Extremely Low Compared to STM32WL55JC1 DK (RSSI -100 to -115 dBm)

We are currently using the STM32WL5MOC module and are facing a serious issue with LoRa range. The communication range is not going beyond 1 meter, and the RSSI while receiving TX data is in the range of -100 dBm to -115 dBm.The same firmware and conf...

STM32WLE5 - How to use sub-band AU915_CH8_15 in LoRaWAN?

Hello ST experts,I’m working with an STM32WLE5CC using the LoRaWAN stack in STM32CubeIDE. Even though AU915 is selected as the active region, the device always transmits on the default sub-band AU915_CH0_7, while my gateway is configured for AU915_CH...

Documentation Error re UARTs on B-WL5M-SUBG1 schematic

There appears to be mislabeling of PINs PC0 and PC1 on the MB1779B schematic pack. found here on sheet 3 of 8. The PC0 and PC1 pins are mislabeled as UART1s but according to the datasheet for STM32WL5MOC they are actually LPUART1 as Alternate AF8....

Resolved! STM32WB55MMG SPI slave doesn't receive when BLE advertising starts

I'm using a custom board with an STM32WB5MMG acting as an SPI slave. The board should receive data frames from a master via SPI, and send them to the computer via BLE. The SPI works fine, but as soon as the BLE advertising starts, the SPI reception b...

Resolved! Question about WB55 Nucleo ADC example

I'm trying to implement the ADC to get V_BAT. I've done the set up in CubeMX in the IDE.I then went to the examples to see how a single ADC reading was done. I'm confused about the use of the following variables... /* Variables for ADC conversion dat...

STM32WBA55G-DK1 audio transmission Query

Hello, I have a query that can we send or stream the audio instead of Linein or Audio Jack, can we send it through CN12 or CN11 pins (UARTor SPI) from external UAC supported device in I2S format? If yes, could you please help me to configure it. I am...

NUCLEO-WBA55CG: ISM330DHCX init fails at ISM330DHCX_Set_Mem_Bank with X-NUCLEO-IKS02A1

Hello,I have been working with a NUCLEO-WBA55CG board and the X-NUCLEO-IKS02A1 expansion board. When running my initialization code, the program execution jumps to the error handler. Using a debugger, I've pinpointed the failure to the ISM330DHCX_Set...

Unable to get Core ID, No STM Target Errors

Hey there I have seen a few posts on this and tried a number of things:1 I went through the process in the user manual and get the error shown2. I tried to reboot board with the jumper moved to boot mode. I put it into UART mode but then got similar ...

Resolved! OTA firmware built using Cube 1.23 not compatible with earlier installed BLE_Ota bootloaders

This is a big problem for me, as I have thousands of products out there using the older BLE_OTA bootloaders, bootloaders which themselves are not updatable by OTA. I have a custom phone app for iOS and Android that interfaces with these products an...
