How to change BLE Access Address without using Low Level Driver
How do I change the BLE Access Address?(default 0x8e89bed6)LLD can be changed through a function called HAL_BLE_LLD_Configure, but there are no functions to change the channel and access address other than that.Is it possible to change the access add...
Resolved! STM32WB15CC
Hi,I'm using the Nucleo-WB15CC board to develop a LowLevel and Lowpower BLE application. The application will sleep 1 seccond, wakeup and send some custom data and then sleep again. Is it possible to have OTA support in this kind of application? Are ...
Resolved! Regarding Transmitting Data Packets using LoRa (CMWX1ZZABZ)
Greetings,I am using Murata Module and LoRaWAN_End_Node project for my project application which I got from STM website . My code is working fine and transmitting data packet successfully with a specific interval of time.Now I want to send another da...
STM32WB55 boot at 1.8V then switch to 3.3V?
Is it possible to boot at 1.8V, have processor configure external PMIC to go to a 3.3V setting and then run the processor at that setting? Any gotchas/things to worry about on the STM32 side and does the processor even care if its supply ramps up lik...
Resolved! PWM dosen't work when using external cystal clock.
저는 cubeMX와 IDE를 사용하여 PWM 신호를 생성하려고 합니다.32MHz 내부 클럭 소스(MSI)를 사용했을 때 PWM 신호 생성에 성공했습니다.블루투스 모듈을 사용해야 하기 때문에 클록 소스를 외부 수정으로 변경했는데 PWM이 더 이상 작동하지 않습니다.누구든지 이것에 대한 해결책을 알고 있습니까?
STM32WL55JC1 is not sending or receiving
Hello everyone, I am using 3 STM32WL55JC1. One for base station and the other two's for sensor node. Everything was fine but then I started UART communication between base station and ESP32. I started coding ESP32 so I unplug the usb cables of stm32w...
BLE Data Throughput Issue - STM32WB5MMGH
Hi,I have been using STM32WB5MMGH for transmitting PCM Data. I used BLE data throughput method from the example code for transmitting data. Audio sample rate is 8000 Hz, that 8000 data is transmitted in a buffer size of 244. The sample is of 16-bit i...
P-NUCLEO-LRWAN2 sensor board - problem with all-zeros AppEUI.
I just got my P-NUCLEO-LRWAN2. I'm able to get the gateway running, but I'm facing troubles with the sensor board.The NUCLEO-L073RZ should already be flashed with firmware that reads EUI parameters from the I-NUCLEO-LRWAN1, and I was able to read the...
I-NUCLEO-LRWAN1 wrong APPEUI
I just bought a LRWAN2 pack, I was able to connect the gateway to the TTN network and application server. But the APPEUI i the join request was wrong (only zeroes). So I plugged an oscilloscope on the RX and TX pins an it shows that:Does this mean th...
STM32WB BLE packet missing and INSUFFICIENT_RESOURCES
Hello all,We are using BLE to send packet of 23 bytes every 5 ms. Since we have noticed that some packets are lost, we are trying to investigate to understand what's happened. In addition to lost packets, for almost every packet, we get the error BLE...
