Resolved! If the power is cut, is the micro controller use battery power automatically?

I'm developing STM32WB55VQ power system but I wonder the microcontroller automatically use battery power or not when Vdd is cut. Is there anybody can explain this?

Resolved! Missing command ACI_HAL_TONE_START in BLE full stack 1.13.3

Hello,From 1.13.0 to 1.13.3, the command ACI_HAL_TONE_START was removed (get Unknown command return). The release note indicates that some HCI commands were removed not ACI commands.Is it an error or should we prepare to move to the full extended sta...

How can I reconnect my ZigBee device to another hub?

[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...

Hi, I use Zigbee_OnOff_Router_NVM. If I call a APP_ZIGBEE_ZbStartupPersist(zigbee_app_info.zb) function and don't call a APP_ZIGBEE_NwkForm(void) function the device will try to connect endlessly and when the connection is restored it will connect.

How can I interrupt the connection process?

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...
