Hi.. Geeks Hope all are doing well I'm using STM32WB Cube FW version 1.13.2 with FreeRTOS I'm facing a very weird issue for a few days Actually, I have allocated one GPIO as a sensor trigger with the Load switch Initially, GPIO is working well before...

STM32WB5MMG short-range joining network

Zigbee test using 1xZC and 1xZR.For ZR to join network, the distance to ZC was limit to arround 2m. After join network, the distance ZR message to ZC can be extended to about 20m.Not understand why the join distance so short. Here's my test setup: ...

Resolved! Need an Ultra Low MCU which has RTC with 32-bit sub-second wakeup counter

Hello,I am currently using STM32WLE5CC MCU, which has a great feature of RTC with 32-bit sub-second wakeup counter, But I need a low cost MCU for my other non lorawan project, which also need this "RTC with 32-bit sub-second wakeup counter" feature.P...

How to save LoRa key context into the flash so that it don't have to send the join request every time it wakes up or restart?

Hi! I'm working on STM32WLE5JC micro-controller. Is there any way to write the firmware in such a way that I don't have to send the join request every time the controller wakes up or restarts?I mean when I first time join the network, what are the sp...

Resolved! Bluetooth low-energy advertising does not start on a custom board.

I'm trying to make my custom STM32WB55 board.Recently, I succeed to start programming the STM32WB55VGY6TR but the advertisement of custom Bluetooth low energy does not start. I tested programming the Nucleo-WB55 board with the same coding and it was ...

STM32WLE5 frequency deviation for FSK modulation

Greetings,what is the recommended frequency deviation parameter for the FSK modulation with 250 kbps bitrate?Or rather what is the dependency of RX sensitivity in relation to the FSK_FDEV parameter?I can see that the limitation is to have the modulat...

Resolved! LoRaWAN_End_Node: varying configuration

Hello everyone,I am now working with LoRaWAN_End_Node on Nucleo-WL55JC1 and I found no place to change configuration such as BW, TX power, Spreading Factor, etc. in this example (Probably, I found at wrong places).Is it possible to change those facto...
