Hi,I have a board which has a STM32WB55RGV6 MCU and i have a problem. When i connected my board to Power supply, it consumes just 13 mA. But then suddenly, it increased 94 mA. I measured resistance between GND and VDD_MCU pins. I was 53 ohm. I unders...
Hi!I've some doubts about security features of stm32WB.After reading the documentation, forums, etc; I can find that stm32WB implements all 4 security levels of Security Mode 1, which includes the ECDHE P-256 cryptography.I've some questions about th...
Hello all,We are developing a product that connects to a mobile application through BLE. Sometimes, not all the time, the product does not connect to the smartphone the first time, it retries to connect until it gets there. As a consequence, the conn...
Hello,Is there any way to catch ACI event dedicated to read NOTIFY characteristic?I tought about ACI_ATT_READ_RESP_EVENT event, but I'm not sure if it is correct if I use with notify Characeristic.Could you confirm me that is a good way to achieve wh...
Hi I am planning to use the BlueNrg module in my project , until I found out that I have to pay for the Qualification fee for using BlueTooth. Not sure if I dont display the logo I dont have to purchase it, or do I have to purchase it even if the lo...
Hello,I have a board with stm32wb55 used as end device, I've tried to enter standby mode after connecting to zigbee network.I found out that if HSE is selected as RF wakeup clockPeriphClkInitStruct.RFWakeUpClockSelection = RCC_RFWKPCLKSOURCE_HSE_DIV1...
Hi friend,I want to extend the HS_STARTUP_TIME for BlueNRG-1. What is the maximum value of HS_STARTUP_TIME for BlueNRG-1? I saw the datasheet AN4494 it says that "XTAL_startup = XTAL_startup_measured*1.2*1.1*1.3 = 1.716*XTAL_startup_measured". So 19...
I am using the STM32WB5MMG. Once per minute the chip wakes up and performs a measurement, then connects to another device to transfer the data. After transfer is complete, the chip disconnects (using aci_gap_terminate) then waits for 100 ms, then sto...
Adding the TX power as standard on a GAP command.Is it part of some standard (SIG) of just an ST specific implementation? Also please refer to my ticket: https://community.st.com/t5/wireless-mcu/advertisement-start-without-automatically-adding-a-tx-p...
Good morning.I have an application where I want to have a Zigbee stack and a BLE stack both loaded on the STM32WB55. Is this possible? I would like my application firmware to be able to communicate with either stack exclusively depending on certain...
