Hi all, I want to do some tests to simulate "low coverage" conditions How could I quickly make the equipment transmit at less power? For example in the EU868 region limit to 10dBm instead of the 14dBm that is allowed, or in US915 to 20dBmn inst...

Hi, We have encountered the following situation: Once the equipment is Joined to the network, if by chance there is a power cut that affects the Gateway and it restarts, we have realized that we stop receiving data from the device. Our Device can ...

Hi all,I read this advertising in the datasheet:<<The SMPS needs a clock to be functional. If for any reason this clock stops, the device maybe destroyed.[...]Danger: Before enabling the SMPS, the SMPS clock detection must be enabled in the sub-GHz r...

Hi all,How can I launch a request to synchronize the date/time at the application level using the LoRa's Stack that the STM32WL uses?I have seen that there is a function to launch that request, but it is not accessible at the application level since...

We design a new product where we use STM32WL microcontroller and in the datasheet ST is recommended to use NT2016SF-32M-END5875A manufactured by NDK but we dont found it to buy.Can you provide some distributors where we can buy this TCXO?Can you prov...

Hi, So, wouldn't it be better if what I want is to change the maximum power in dBm, directly modify the EIRP of the region?Best Regards, Sergio

Hi,In this application note:https://www.st.com/resource/en/application_note/dm00660451-how-to-build-a-lora-application-with-stm32cubewl-stmicroelectronics.pdfI read that SMPS is also named DCDC And searching DCDC in the End_Node source code I found:i...

This is a ST Advertising... Nothing to comment about it?

Hi all,In order to set the time synchronizing with the network, what I have had to do is:Put the function LmHandlerErrorStatus_t LmHandlerDeviceTimeReq(void); in the .h to give it visibilityAnd when I want call this fuction before LmHandlerSend() to ...

No, we have not considered using a a regular 32Mhz HSE because temperature variations will be constant, not only because the equipment will be outdoors, but also because the RF circuit produces temperature increases.
