I-CUBE-LRWAN don't work on custom board: PHY txTimeOut ERROR

Helloi made a customised board using the STM32L476RETx mcu with a lora module : DORJI DRF1262TI opened the project from i-cube-lrwan expansion package with the name SX1262dvk1das USING THE SX1262 AT 868MHz.i updated the PINOUT of my MCU and exclude a...

STM32WB getting stuck into Hard Fault on unsuccessful Bluetooth connection attempt!

We have tried usingNVIC_SystemReset();but it seems it only resets the M4 core and not the M0+ responsible for Bluetooth communication. It would be really appreciable if someone could guide us towards identifying the cause behind this behavior, and ho...

STM32WB55 Thread FTD Wireless Stack (v1.10) not ACKing when ot command sent

It appears that v1.10 of the Thread FTD binary does not work properly. When a command is sent (line 4 below), the code stalls in an infinite loop, waiting for an ACK from the M0 processor.static void APP_THREAD_DeviceConfig(void) { otError error; ...

Resolved! UART example for STM32WB55 "printf" prints gibberish. I see, the characters are sent to "HAL_UART_Transmit" are correct. BLE HRT example prints debug messages correct.

The printed message is:▒▒RT ▒▒▒n▒▒ E▒amp▒▒ ▒▒▒a▒g▒▒ ▒h▒ C ▒▒b▒a▒y p▒▒n▒▒ ▒un▒▒▒▒n ▒▒ ▒h▒ ▒▒RT▒Insteadprintf("UART Printf Example: retarget the C library printf function to the UART\n\r");

Resolved! BLE: detect security level

Hi,i have 2 boards (client and server) with STM32WB that communicates through BLE messages. Right now, at every reboot/disconnection i am redoing the pairing, but it is really slow.In order to reduce the whole connection time, i am trying to use the ...

How to initialize GPIO pin and interrupt with ICube-lrWAN package.

i want to initialize pin A9 & A10 in BL072ZLrWAN1board of STas a external interrupt pin. ICubeLrwan package not integrate with cubeMX so i am confuse about how to initialize the pin and call the interrupt and write its callback function.

[SOLVED] Flash Write/Erase mechanisms behaviors, Cube examples reliability

Hi,We are currently working on an usb composite library but some old FLASH ghosts reappeared.When sending data through a cdc flash started to fail some erase/program.We decided to upgrade our Wireless stack to latest (1.10.0) from our current 1.6.0 (...

Hi, i want to send a small message (tick) from STM323WB to a phone, at every connection interval. How I can sync a timer with a connection interval? Is there any event on connection intervals?

Does SRAM2 parity work with the BLE stack?

Greetings,My application for the STM32WB uses the BLE full stack from v1.8 of the Cube. I just noticed that there is a v1.10. I plan to test this as well, just in case this has been fixed.The cube has code to manipulate the SRAM2 parity options, but ...
