Hi, I am trying to measure the power consumption of my NUCLEO-WL55JC2.In the user manual here Is what I found : Jumper JP1, labeled I_SoC, is used to measure the STM32WL microcontroller consumption by removing thejumper and by connecting an ammeter....
Hello ST community, I am leading a project at university and I would like to make a communication between two STM32WL55JC1 cards using the LoRa protocol without a gateway. I'm not very familiar with STM32CubeIDE and any help would be much appreciated...
Good morning,I am building a system with stm32 wl55jc1 to count water flow with a pulse flow meter.So I created two internal clocks in stm32 one to create a time window and the other that counts each pulse received from the sensor. At the trigger of ...
I have been getting warnings similar to the following when I link with LinkLayer_BLE_Full_lib.a and stm32wba_ble_stack_full.a. output.axf is the executable elf file. objdump is from Ubuntu 23. objdump -g 'output.axf' > 1.txtobjdump: Warning: Inval...
Hi A previous version of a product used STM32G071x8/xB in conjunction with external radio transceiver (SPSGRF-915). The team has used SPIRIT middle ware for radio functions. A newer version has migrated to STM32WLE5/E4xx which has inbuilt radio and I...
Hi,I am using aSTM32WB55Wireless Firmware version 1.17.2Wireless Firmware build 1FUS version 1.2.0As described by AN5270 2.5.6. an ACI_GATT_UPDATE_CHAR_VALUE must fire an ACI_GATT_NOTIFICATION_COMPLETE_EVENT if the characteristic was created with GAT...
In my design I left the exposed pad in Stm32wb55rg VFQFN68 package. when I try to flash the device using st link , iam getting error "target not found". I am check the design and found i left the epad (69th pin) floating. Does this cause any issue ?....
I am attempting to use the https://github.com/stm32-hotspot/stm32wb-matter-device-over-thread/ repo to connect a STM32WB5MMG-DK to an Amazon Alexa acting as a border router, using the Alexa app. The device always fails to connect, outputting the seri...
Hi,I have made an application on that needs to enter shutdown/standby mode on the STM32WB10 MCU.I have successfully made it enter the shutdown mode, and I can wake it back up again.However, when it wakes up, it does not get any response from CPU2.It ...
Hello! We are a bit stumped here. We have a product that we are testing at 65C and it seems that the bluetooth connection keeps dropping at this temperature (Connection timeouts). We are running from a 32K LSE and 32M HSE crystals. All our parts ...
