Zigbee with standby mode

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...

What is the maximum value of HS_STARTUP_TIME for BlueNRG-1?

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...

aci_gap_set_non_discoverable intermittently returns `COMMAND_DISALLOWED`

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...

STM32WB55 dual stack?

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...

Advertisement start without automatically adding a TX power type

Hi, Hi all!My first post here and very excited! We just switched to ST Ble module in stm32wb55. Now I am trying to remove AD_TYPE 0x0A from advertisement, it takes us 3 bytes we need.Similar to this issue : https://community.st.com/t5/wireless-mcu/p...
