I'm trying to use the STM32WB example project Zigbee_OnOff_Client_SED on the P-NUCLEO-WB55.Nucleo. Unfortunately, as soon as I load the Zigbee RFD firmware on the coprocessor of my SED the device isn't able to join the network created by the coordina...

Resolved! Powering NUCLEO WB55 externally

Hi! I have a nucleo WB55 board that I am using for a project. I know with other nucleo boards, it is possible to power them externally with 5V or 7-12V. However, I am not able to verify whether this is possible on the NUCLEO WB55 board, as I can't fi...

Resolved! RSSI on LoRa-E5 vs nucleo-WL55JC1

Hii'm just sitting and messing with a few lora boards.I find that nucleo-WL55JC1 has approx 10dbm RSSI better than seeed LoRa-E5, and that nucleo-WL55JC1 also transmits with a more powerful signal, what is your experience ??with best regards

STM32WLE5 doesn't work SubGhz module on custom board

Hello,I create a custom board from the reference MB1791. But when I try to run an example for the Lora SubGhz module - it doesn't work, no interrupt, no transmit to the antenna (watch in SDR).I ran this example code with RAK3172 (also a custom board...

NUCLEO-WL55JC1 Packet Loss

Hello,my setup consists of 2 NUCLEO-WL55JC1 boards and an adapted version of the example project SubGHz_Phy_Per with which I can recognize the number of bit errors, RSSI of the latest received packet and some interrupts (IRQ_RX_DONE, IRQ_PREAMBLE_DET...

Lora Concentrator board and custom board on STM32WL55cc

Hello!I'm trying to port of LOcalNetwrok_Concentartor on a custom board. I made USART1 working with a tracer. So i Can send and receive AT_Commands to a MCU STM32WL55CC. Now I'm struggling with getting interrupts from a LoRa modem. Every 15 sec I cal...
