Resolved! Need M0+ recovery solution without reseting M4

Hi! We are developing a sensitive device using the STM32WB55, using in the M0+ the concurrent Thread+Ble binary (we use the concurrent because we'll need both Ble and Thread in the near future, althought the most important role is the Thread communic...

HAP Central start stream fail

Use example code BLE_Audio_HAP_Central to audio function. The Central may start the stream fail, though the BLE connect and GAP link returns are OK. and Once the stream start failed, the stream cannot be start forever, with the result "CAP Unicast St...

LORA TX CURRENT CONSUMPTION numbers specified in the datasheet

Hi,I have couple of questions regarding the LORA Tx numbers specified in the ds for the stm32wle5.we are using VDD=3.3V , 22 dBm , ~928 Mhz LORA. 32 Mhz TCXOwe are NOT using the SMPS . table 29 in the ds mentions that typical current for...

Resolved! 2.4Ghz Comms Example?

Hi.,Could anybody point me to a working example of a working basic IEEE 802.15.4 communication example, NOT Bluetooth, pure radio frequency in 2.4Ghz.I spent about 2 months trying to figure this out for my WB55 series without success and can't waste...

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...
