HCI_COMMAND_COMPLETE_EVT_CODE cannot be received

BLE peripherals are implemented using NUCLEOWB55RG.I would like to check if Advertsing is working properly by receiving the completion of the asynchronous aci_gap_set_discoverable execution with HCI_COMMAND_COMPLETE_EVT_CODE, HCI_COMMAND_COMPLETE_EVT...

Use flash memory area between (origin + length) and Wireless Coprocessor Binary start address

The STM32WB5 has 1M of flash memory. The default linker script shares this 50:50 between main and second core (LENGTH = 512K), meaning flash ends at 0x0808 0000 (page 128) for the main core.But the wireless binaries don't necessarily start right at t...

Resolved! Seek advises and reading materials on designing lowest power system using STM32WLE5JC

Please advise on Application Notes, Training, examples on Evaluation board, etc. on designing lowest power system using STM32WLE5JC. Cell life for weeks or months. I intend to use STOP2 with RTC and normal-run modes.I found App Note 5568 and 4879.M...

STM32WL DAC Sample-And-Hold: Internal capacitor?

I want to generate a constant, steady voltage as COMP INPM in STOP1 with the DAC (using HAL libs at the moment).Unfortunately I cannot get a steady signal. The voltage drifts around some seconds, stabilises and starts from the beginning (oddly seems ...

SIGFOX_API_start_continuous_transmission

Using this API returns 0x3157 error code after running SIGFOX_API_close successfully (return code is 0), anyone tried that? What are we missing here?BTW - Same behavior observed when using ST provided Sigfox_AT_Slave_DualCore example out of the box w...

STM32WL on Class C mode stops processing Rx commands until next Tx

Hi, I'm using STM32WLE5CCUx MCUs with STM32Cube FW_WL_V1.3.0 firmware package. The nodes (~ 20 nodes) are working in LoRaWAN Class C mode and MAC version 1.0.4 (US915, no duty cycle restrictions)The issue I'm experiencing is that from time to time in...

Resolved! STM32WL55 dual core debug _ error 18 when debugging CM0+

Hello,I have started to use stm32wl55 nucleo.I try to debug a basic application.I start by debugging CPU1 (CM4) than after booting CPU2 (CM0+) i run the debug for the second CPU.But ST-LINK: Could not verify ST device!error details :Error in final la...

Possible values for ACI_GAP_IS_DEVICE_BONDED response packet

Found below what I assume to be the Possible Values for 'Status' , but not sure, any other? 0x5C Device not found in DB0x5E Device not bonded Can you list all of them?Or are those values in the Bluetooth Specification? If so can you provide a link? ...

Where to go next with STM32WB using the B-U585I-IOT02A

Hello,I've been recently starting to get into the STM32 ecosystem using the B-U585I-IOT02A discovery board, first by toggling LEDs and GPIOs but eventually trying to get familiar with how to use the integrated STM32WB5MMG module.I was able to get a d...

LocalNetwork Demostration problem

Good morning,I am using two NUCLEO WL55JC1 development boards and the LocalNetwork_Sensor and LocalNetwork_Concentrator example that I found in the development software provided by ST. When I use a frequency band of 868MHz and a bandwidth of 125 KHz ...
