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 ...
I use STM32WL RTC Alarm as low power mode timer for achieve ms level accrancy and any duration sleep. System will convert sleep time to Alarm time before enter low power mode. I have tested different sleep time, verified convertion result is correct...
Hi ST experts.I used the pingpong sample code to test RSSI and SNR. I set SF=12, BW=62.5Khz.I used SX1261 calculator tools to calculate, under this condition, its RSSI can reach -140dBm.But during my actual test, our RSSI reached -120dBm and the SNR ...
