Resolved! FUS_STATE_IMG_NOT_AUTHENTIC error updating FUS from 0.5.3 on STM32WB55
I'm trying to upgrade the FUS and wireless stack version on my STM32WB55 Nucleo board via ST-LINK using STM32CUBE Programmer GUI tool and seeing this error message FUS_STATE_IMG_NOT_AUTHENTIC. I'm using "STM32WB5x\stm32wb5x_FUS_fw.bin" to upgrade the...
Resolved! LoRaWAN integration in STM32WB55
I am using the STM32WB55 microcontroller where I use BLE and integrate my main program with code that I am implementing.On the other hand, I need to use LoRaWAN and for this I use the HOPERF RFM95 module in which only the radio part is integrated but...
STM32WLE5CC Hangs on Flash Write when High frequency External GPIO Interrupt is enabled
Hello,Our application is to count fast external interrupt with denouncing in EXTI_callback().only When this interrupt is ongoing and try to write flash ,then STM32WLE5CC hangs, and reboot using Independent watchdog.Write to flash code:void emulated_e...
How to check the connection state of BLE?
Hi,I'm using stm32wb55 for ble application.I want to check the connection state of BLE for conditioning case.Is there any global instance or register which contain the state of BLE?Thanks.
What is the STM32WL55 LDO mode output capacitor value on the VFBSMPS pin?
The datasheet indicates the value of 470nF for the SMPS mode on the VFBSMPS pin. But for the LDO mode, I didn't find the required value.Thanks

Why does aci_gap_set_discoverable() return Command Disallowed?
Under what circumstances will the BLE controller return Command Disallowed (0x0C)? I am calling aci_gap_set_discoverable() followed by aci_gap_update_adv_data() periodically. I see aci_gap_set_discoverable() return successful the first time that i...
Wait until BLE notification has been sent
I basically have this code:while (...) { // A while (BLE_STATUS_INSUFFICIENT_RESOURCES == aci_gatt_update_char_value(...)) { // B osDelay(10); } } while (BLE_STATUS_INSUFFICIENT_RESOURCES == aci_gatt_update_char_value(...)) { // C osDelay...
IRQ handler not being called anymore after exit from low power mode (stop2) on the STM32WB55 Nucleo board
Could anyone please help me with this problem? Thanks in advance. I am using the low power manager (lpm) interface generated by MX for the STM32WB55 Nucleo board. I am using HSE as system clock source, so I did not make changes to the two functions P...
