STM32-WL55JC: "Cannot use executable file as input to a link" issue
Hello.I'm trying to run this LoRaWAN FUOTA code: github.com/ SylvainMontagny/STM32WL/tree/main/STM32WL_FUOTA (that's the Single-core project on the Application Note AN5554), but i get the following error:c:\st\stm32cubeide_1.9.0\stm32cubeide\plugins\...
Resolved! Do the STM32WB Nucleo boards have the HSE crystals pre-calibrated from STM?
I am a hobbyist that only has basic oscilloscope and function generator that is (according to AN5042) not accurate enough to tune the HSE crystal. Is the HSE crystal in the NUCLEO-WB55RG pre-tuned?
BLE_HeartRate application consumes more power on STM32WB5MMG than expected
I have tried running the BLE_HeartRate application as generated by STM32CubeIDE v1.11.0 which used WB FV 1.15.0. I am running on a custom board (DK board is not available right now) that has a STM32WB5MMG module, the recommended capacitors, and a he...
Writing to address 0 prevents from entering shutdown mode
If I write to address 0, it prevents from entering shutdown mode.The vector table is relocated to code.As far as I understand, writing to address 0 in this case is not illegal. For sure it does not generates a fault.The following code enters shutdown...
Resolved! How to change TCXO to Quartz Clock configuration SW LoRa_AT_Slave
Hi, I would like to try nucleo-WL55 in LoRa Node with Quatz and see temperature influence in RF signal.So I have unsolder R2, and solder R39/R40. But now LoRaWAN_AT_Slave does not work anymore, even if I change TCXO to Quartz in .ioc file. I can see ...
Resolved! Wb55 - How to read values from ADC
Hi everybody!Working on Martian Robot développed by VittaScience, I need to read values coming from 5 blackline sensors to the ADC of the wb55.I tried to analogRead() the pin but nothing...Some ideas? Thanks!
Resolved! Correct procedure for reading BLE characteristic values.
I am currently trying to read the value from a characteristic after detecting that the user has written to it. I am calling aci_gatt_read_char_value() which is returning 0 (BLE success). From here I am expecting an event which triggers the aci_att_r...
source: en.fp-aud-bvlinkwb2.zip I want to output the Central's USB output to the codec chip (sgtl5000) through the SAI interface.
Voice is heard through the codec chip, but the noise is severe.There is no noise when you listen to the voice from the PC through the USB output.I don't know if the SAI setting on the Central is wrong or the codec chip setting is wrong. If you playba...
RNG access after starting BLE stack
It looks as if the RNG is made unavailable to the M4 when the M0 has booted the BLE stack. This looks to be true because I can initialize and use the RNG before starting the BLE stack. Once I launch C2, the RNG registers read as zeros.Is this a req...
