AD5129 - meander design for STM32WB Series Layer Stack Double Check
Hello,I am developing a custom board with the STM32WB55RGV6 Chip and an on-board PCB antenna. The document is for a 2-layer PCB and I am needing to do a 4-layer PCB. I don't completely have the recommended stack-up, but altium shows its very close to...
Resolved! Integrating AT Slave example of LoRaWAN and Sigfox on STM32WL
Hello developers,I am currently developing all in one AT Slave firmware for STM32WL, which can handle both lorawan and sigfox AT commands. I have tested both AT Slave example of Sigfox and LoRaWAN one by one and it's working as expected. When i open...
Resolved! simple project work on P-NUCLEO-WB55 but not on custom pcb
I've prepared a small device firmware for a STM32WB35CEU7Ait's only providing battery service and debug infos on serialI've tested it on a P-NUCLEO-WB55 loaded with stm32wb5x_BLE_Stack_full_fw.bin1.19.02 stack loaded @0x080CE000 and it works wonderfu...
Resolved! BLE insufficient resource - error code 0x64
Hi,I am writing a client/server application for STM32WB55. Server behavior is ok. On client side, I connect to a peripheral and try to send 32 bytes packets every 100 ms on peripheral's RX characteristic using aci_gatt_write_without_response function...
PLL clocks for P-NUCLEO-WB55 sleep
What is the correct way to configure PLL in clocks for the BLE_HEAR_RATE_FREE_RTOS example ? So that sleep is maintained?
ZigBee stack without malloc
Hi,For our embedded Zigbee wireless application, we want to use the ST Zigbee stack.Per design, we want to avoid the use of dynamic memory allication. Per default, the ST Zigbee stack internally seems to use malloc for memory allocation. The ST appli...
Resolved! Problem connecting STM32WL to sigfox network
Hello Developers,I am currently testing Sigfox AT slave example from STM32Cube_FW_WL_V1.3.0 on STM32WL nucleo board. I already have 5 set of ID,KEY,PAC values from sigfox build for testing purpose. But when i am running sgfox at slave example, i a...
Resolved! Connect STM32WB55RG via Bluetooth to RN42
I want to connect my NUCLEO board via bluetooth to a RN42 bluetooth module. The RN42 recieves sensor data from an adruino and needs to send it wirelessly to my STM board. How can i go about connecting the two?
EEPROM Emulation for STM32WB55 Example missing
HiI`m working on a customised STM32WB55 board and trying to implement eeprom emulation.According to AN4894there should be a BLE_HeartRate_EEPROM_Emul example somewhere but looking at STM32Cube_FW_WB_V1.12.0 package I can`t find it. I have also checke...
