Hi,My application (WB15CC) stays most of the time in standby mode transmitting the advertainment packet. After a couple of minutes, the advertainment packet must be updated. When I try to update the packet after waking up from the standby mode, the f...
Good dayI am using the STM32WL55 chip for a project. I did preliminary tests using the NUCLEO-WL55JC2 Development board.I created a custom PCB following the design of the Development board.When I program the custom board with the same firmware that w...
I find that when entering deep sleep/range 2 using aci_gap_set_non_discoverable(), C2 would not reliably enter the ultra low (~4uA) power consumption mode, current would jump to ~5mA. I am using stack 1.18 and even 1.19. a) Calling aci_gap_set_non_...
I have 2 devices on my SPI bus that need different CPOL settings. both use CPHA = 0 and the SPI peripheral is configured to use Motorola frame format.Communication works with both devices if their respective CPOL setting is set in CubeMX (and thus fi...
H,I just had some custom boards with STM32WB55CG and I would like to flash the BLE stack into the microcontroller. For some reason the STM32CubeProgrammer does not allow me to flash the FUS or BLE stack files, it always comes back with warning/errors...
I am developing a BLE peripheral device using the NUCLEO WB55RG. I am having trouble connecting to smartphones. The pairing process is as follows: The security is Just Work, using bonding mode.During the first pairing:The peripheral sends a security ...
I am trying to include a tinycbor .h file and as per third party include method i have done all the step but still i get the error about the linker didn't find a definition of library API functions. Here is the all the screenshot of my project and lo...
Hello everyone I've encountered an issue with connecting to Linux, specifically Ubuntu 22.04, while the Linux device is acting as a BLE gateway running the Bleak python library to manage connections. The firmware used was loosely based on the instruc...
Hi allI'm new on stm32 ble applications.Starting from st example BLE_OTA I developed my custom bootloader for my STM32WB55 nucleo board.I encountered the following issues:1) St ble sensor mobile app (from play store) can't detect my device; I compile...
Wondering what is the cost of using SHCI_C2_BLE_INIT_OPTIONS_REDUC_GATTDB_NVM overSHCI_C2_BLE_INIT_OPTIONS_FULL_GATTDB_NVM ? The first one can gets me 33% increase in bonding list size but I could not find what does it prevent me from using?
