[STM32WLE5CC] Firmware behavior according to power
Currently, we are using the STM32WLE5CC MCU.Some MCUs do not operate normally when the same firmware is inserted into several MCUs. (Abnormal current, delays in Uart log output, RF is not transmitted)If a higher voltage (4.4V) than the MAX operating ...
Resolved! is it possible apply higher power in VDDRF? For example I can apply 4.2 V.
I'm designing power supply part of STM32WB55 microcontroller.I'll use a Li-ion battery for power supply of STM32WB55 microcontroller.As we know, the microcontroller requires 3.3 V maximum but Li-ion battery can generate maximum 4.2 V. So, I'll use in...
STM32WLE5CC (RAK3172) LoRaWAN end node unable to reduce power below 150uA
I have created this easy project for the RAK3172 based on the LoRaWAN end node skeleton (myIoTopenTech/TiposDeDispositivos/TTNMAD_SOUND/STM32CUBEIDE/ttnmad_noise/) available on GITHUB.The program works properly joining to The Things Network using OTA...
Why my HS_STARTUP_TIME is so high?
Hello,I'm doing a new board bring-up and following the document AN5503 (https://www.st.com/resource/en/application_note/an5503-bringing-up-the-bluenrglp-bluenrglps-devices-stmicroelectronics.pdf)At chapter 4 (HS_Startup_time) I use the example firmwa...
Making BLE Application lossless on STM32WB5MMGH
We have implemented BLE application on STM32WB5MMGH. I see that some of the BLE packets are getting lost in transit. The peripheral and the master are in very close proximity. I understand that packets can get lost depending on environment but my que...
ZigBee messaging: how to send more than 59 chars per message?
Hi.I would like to send in the worst case 750 chars through ZigBee.Issu: I can send only 59 chars per zigbee message, using Messaging cluster.After reading the ZigBee specification, it seems that this cluster handles sending more than 59 chars, by fr...
Resolved! Should I connect all the ground pin in microcontroller?
If I see the pin layout of STM32WB55VQ,There are multiple VSSRF, VSS, and VDD like below.If I want to see proper function, should I connect all the VSSRF, VSS, and VDD?or is it fine connect only one of them (For example, one ground on VSSRF, one grou...
Recommended way to create project with HAL drivers without using code generation in STM32CubeIDE?
I am trying to create a project that takes advantage of the HAL drivers, but does not include auto generated code. It would be ideal to be able to tell the IDE which HAL drivers to include and start off from there. Unfortunately, I could not find suc...
