Hi, We are trying to write some key values directly into a particular address of NVM from STM32Cubeprogrammer, but rest of the sector are also getting erased. Is there any way to prevent it? Tested with Cubeprogrammer CLI also, but facing the same is...

Hi,In RAK3172 which have STM32WLE5CCU6, during the flashing of DEVEUI,JOINEUI ,APPKEY and NWKKEY in which memory location of NVM this values are being stored. Is there any documentation for same? Also can we flash these keys directly to NVM using STM...

What are the differences between LPTIM and TIM, also doesTIM1,TIM2,TIM16,TIM17 work when the device is in STOP2 mode?

Hello, I have a RAK3172 which is based on STM32WLE5CCU6, and it is being configured for LoRaWAN, and the node transmission is happening based on timer (TX_ON_TIMER), sometimes an External interrupt will be there and the device needs to send the packe...

Thank you for the suggestion! I’ll definitely look into it.

Sorry, I should have mentioned it.I am using RAK3172 module (STM32WLE5CCU6) for LoRaWAN application.For every LoRaWAN application, there needs three parameters which are DEVEUI,JOINEUI and APPKEY. Right now these are programmed from the firmware itse...

Yes, I mean flash. Is there any other way to do it? So that other flash contents remain as it is. Only a particular selected area gets erased and written.

Thanks, but I have a confusion, what are the difference between these two register addressesis REG_LR_SYNCWORD only used for LoRa, and REG_LR_SYNCWORDBASEADDRESS is generic, like is it common for LoRa, FSK and other modulation techniques?

Thanks for your response, but how can I set my own sync word, default is 0x1424, but let's say I want to set 0x1122, how can I do that? Should I include radio_driver.h file and call SUBGRF_WriteRegister() directly, or there is any other better altern...
