Resolved! Micropython report issue in address resolution
Hi, from the micropython repository there is a note on a problem regarding address resolution, it is reported at this link.Are there any details about it? is this a known and solved problem? or still open?Thanks and regards
Resolved! load capacitance of recommended quartz for HSE lower than minimal load capacitor trimming
The quartz used for HSE on the nulceo-wl55jc and on the reference design for stm32wl is NX2016SA 32MHz EXS00A-CS06465, which has a 10pF load capacitance (the BOM for reference design even mentions 8pF, but the quartz reference is actually 10pF).The m...
how to communicate lora with stm32wle5c8?
Hi everyone,I modified the project https://github.com/STMicroelectronics/STM32CubeWL/tree/main/Projects/NUCLEO-WL55JC/Applications/LoRaWAN/LoRaWAN_End_Node so that my MCU - STM32wle5c8 can communicate with lora but I get the error ("IRQ_CRC_ERROR") a...
Resolved! An error occurs when include any header files in se-identity.h
I have function to receive Dev EUI, APP Key, and NWK Key data from UART. Then, I want to put and replace of Dev EUI, APP Key, and NWK Key in se-identity.h with my own data which I have saved in flash memory. But, an error occurs when only include my ...
Resolved! How to create a new (and very simple) STM32WL project from scratch ?
Hi everyone,I'm trying to convert our IoT Sigfox sensor from EFM32 to STM32 architecture.As a beguinner on STM32, I'm using an LSM100A eval board based on STM32WLE5CC.Can anybody explain me how to create a simple Sigfox project ? I just want to send ...
STM32WB55RG BLE does not work.
Hello~Hello. I am developing a BLE device using STM32WB55RG.The test board I am using is as follows.P-NUCLEO-WB55MB1335D-01After receiving the board for the first time, I wrote Middleware BLE of STM32_WPAN at STM32CUBE IDE, and communication with m...
Resolved! STM32WL55 RF Power Amplifier Impedance & LNA (differential) input impedance
Hi.I need to design a custom board for LoRa 923MHz network.The AN5457 provides the example for 923MHz network. (A.1.6)I can get output Impedance from this example(AN5457).But I can't find LNA (Differential) Input Impedance for UFBGA73 package @923MH...
