Sir, I testing the STM32L0 + SX1276 with en.i-cube_lrwan_v2.1.0 libI compiled the AT COMMANDS example on KEIL and then with STM32 IDE too, but during execution i am always getting the following error in bothAPP_VERSION: V1.1.0MW_LORAWAN_VERSION: V...
Resolved! MB1552B board (STM32WL reference layout) BOM and Schematic ?
It is possible to share the schematic and BOM files of the MB1552B board presented as a design reference in the document: "AN5407 Optimized RF board layout for STM32WL Series" ?
How does FCC certification work for STM32WL?
Will ST Micro pursue that certification on the module/SOC level? Or will vendors have to pursue that certification independently/at the device level?
Resolved! RTC example for timestamp (STM32WB55)
Hello,I'm looking for some example code on using the built in RTC for the STM32WB55 to get a timestamp in UNIX UTC Time in milliseconds. Or the number of milliseconds since January 1st 1970.If anyone has a simple example on how to accomplish this I w...
Resolved! STM32 ADC?
Good morning......I am using the ADC with 2 channels (Ch 9 and Ch 10). I am using an LPTIM to take these samples every 15ms. I have the ADC callback (HAL_ADC_ConvCpltCallback) to interrupt on 'End of sequence of conversion' (per .ioc --- or so I thin...
STM32WB55 Issues with Advertising BLE Name Length Longer Than 9 Characters
We have encountered issue with WB55 BLE firmware where it doesn't accept AD_TYPE_COMPLETE_LOCAL_NAME longer than 9 characters We have reproduced that issue on p2pServer example where we've modified local_name to be "123456789" all is OK.static const ...
Resolved! How to select a USB device at startup?
Hi everyone.I need to activate a different USB device (one only, no multi role) at startup, depending for example on a GPIO status. I have two versions of an application on a STM32WB55 Nucleo board working as MSC in a version and CDC in the other. I ...
STM32WB55 custom board and 32Khz crystal
Hi,I'm creating a custom PCB for the STM32WB55 with BLE functionality and was wondering if in order to use BLE, do I need to include a 32Khz Oscillator on pins PC14 and PC15? I am assuming I do, but did not see anything definitive in the datasheet.T...
