Resolved! How to use the On/Off Router example with ZigBee2MQTT?
Hi,I want to learn ZigBee and for this, I want to see what´s going on in the On/Off Router example and build up an environment to test my own implementations by using ZigBee2MQTT and a CC2531 dongle. I flashed the example onto my STM32WB55 Nucleo and...
Resolved! Is it possible to generate a continuous square wave signal in the GPIO pin without extra order from CPU?
I realized that I would need continuously switching the GPIO pin for external MUX.So, I want to know how to program continuously switching a GPIO pin (with a specific frequency and start timing for synchronizing with other GPIO pins)However, If I on/...
STM32WB55 sometimes returns unknown error value when trying to update a characteristic
Hi,I am using an STM32WB55RCV6 with the full BLE stack.During operation, I am updating some characteristics. Some at the push of a button, some scheduled with a timer.Sometimes, unregularly, and only when the device is connected (to a smartphone), th...
STM32WL55: Subghz RADIO_GET_STATUS returns invalid data.
Hi, i'm currently working on a Project where i need to send some data via LoRa.I've been struggeling to get a transmission going, so i decided to check the basics.To test the radio, i went ahead and rebuilt the SUBGHZ_Tx_Mode example from the STMCube...
