Need 2-layer reference design for 433MHz LoRa
Hello, the reference design STDES-WL5U2SBB (MB1791) specifies a frequency range between 470-530 MHz. I plan to run LoRa on 433MHz with 10 dBm. I do not wish to use a 4-layer PCB in my product design. This seems to be the only version that has 2-layer...
Resolved! Porting STM32CubeWB code from WB55 to WB15 board
In the STM32CubeWB source code collection, I found the BLE_Peripheral_Lite project. This project however is only available for the P-NUCLEO-WB55, but I am working with the NUCLEO-WB15 board.According the Release notes this should be easy:<quote>The p...
Using I-CUBE-LRWAN in a separate project generated with CUBE-MX
Hi,Is it possible to import files from I-CUBE-LRWAN package to a new project generated with MX? From the info I've found so far I know there is no way to import it automatically with Cube MX and I have to transfer them manually but I'm not sure which...
Resolved! (STM32WB55) Generated Binary is too large. Expected <100kB but get >500kB.
I have added a partition (MY_MEMORY) to my flash to store a static library (littlefs) so that I don't have to include it in the firmware that is updated over the air however the output binary file for the project is very large. I have reviewed this p...
Resolved! Advertising timeout and low power advertising with latest CubeMX
I'm having an oddly difficult time seeing how to do something quite simple. In older CubeMX projects, the `Adv_Request` function looked like this: static void Adv_Request(APP_BLE_ConnStatus_t NewStatus) { tBleStatus ret = BLE_STATUS_INVALID_PARAMS;...
How to inspect the clock source for RTC?
I have three STM32WB55 applications:A) is a debugging application that's only ever flashed directly and standalone using the STM32CubeProgrammer CLI.B) is a bootloader with integrated FUOTA functionality.C) is my "actual" application. It can be compi...
Power Consumption Help with STM32wb55
