Wireless stack on custom STM32WB55
Hi all,Im trying to load the stack onto the custom board. I've done it for both Nucleo board and dongle. I use Nucleo board with SWCLK, SWDD, RST, GND, 3V3. I think Ive managed to program FUS as it shows the correct number and it starts. Ive been try...
STM32WB15 test BLE Tx in custom hardware
Hello, I'm Marco, HW developer.Scenario: two Nucleo WB15CC transmit both a sawtooth into the Nucleo WB55 USB dongle with BLE protocol. With a proper SW we can see the two sawtooth in the GUI. The Nucleos WB15 should be replaced with custom HW with sm...
Interference between RTC and LoRa activities in the NUCLEO STM32WLJC1 board
Hello guys, I have this situation where when I use the LoRa protocol in my application, the RTC stops working and vice-versa. Anyone have an idea of what could be causing it and the solution for the problem?
Unexpectedly small L2CAP fragment size in BLE data transfer
I'm working on a BLE application which uses a pair of BLE characteristics to transfer packets of data (similar to a cable replacement service). I believe I have followed the recommendations in AN5289 8.6.9 to mazimize throughput.When I read packets f...
STM32WB55: Zigbee Attribute Reporting - Client and Server
Hi there, I explored the attribute reporting topic based on my initial question, which you can find here: [link]. I gained a better understanding of how the feature operates.Currently, in my setup, the Client pretends to be a Zigbee End device, and...
