How can I validate the LoRa MIC value on the NUCLEO-WL55JC1?
Hi everyone,I am trying to connect a NUCLEO-WL55JC1 to the TTN network. I have specified the device EUI, app/join EUI, app key and network key in the se-identity.h file. The debug output of the board confirms that the values correspond to the values ...
STM32WB55 - how many concurrent timers may be provided by timer server?
As an example, the following code is provided, the timers are started and stopped in app_ble.c.I can run two of the three leds using two different timers and they work properly, but when I add the third one than the leds start working in an unexpecte...
Bootloader for STM32WB55
I have written bootloader for F0 and F1 series. These are pretty straight forward and lots of flavors available on Github. However I cannot adopt the same strategy for the WB55. The reference documents on memory mention a standard bootloader and an O...
Resolved! HW_TS timing is different when appe_Tl_Init(); is called
I have written an app using the sequencer and time server. My app selectively runs or doesn't run the BLE stack by calling or not appe_Tl_Init();I use HW_TS to generate delays. When I don't run the appe_Tl_Init function my timing is correct. when ...
Is it possible to use multi GPIOs based on one common PWM channel?
In my project I uses 2 LEDs and one Buzzer, all of them based on PWM controlMy current HW implementation is as follow:Led#1 connected to PA.3 - PWM based on TIM2/CH4Led#2 connected to PB.9 - PWM based on TIM1/CH3NBuzzer connected to PA.0 - PWM based ...
How do I: a) get into standby mode after running BLE server app? b) start the sequencer without starting BLE?
I am trying to write FW for the WB55 which starts a BLE server on powerup ( so far so good)then after BLE connected to and a characteristic has been written and BLE disconnected I want to be able to enter standby modeUpon an RTC wakeup the FW will se...
Modification of OTA Control in The Firmware
Hi,I am currently using STM32 custom board with STM32CubeWB. I am a newbee in writing the firmware. There were two versions of binary files I got from previous programmer, one is with OTA function and one is without OTA function. They were uploaded i...
STM32WB cannot connect to the phone using code from cubemx
