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...
