STM32WB55 BLE OTA issue

Hi,I am working with OTA on STM32wb55 wireless MCU,I have tested BLE OTA from android app mentioned in AN5247 and it worked well.Now i need to create a python app doing the same.In order to do that i followed Flow given in the same AN5247 at Figure 9...

the current consumption of the STM32WB55 in stop2 mode is about 116uA whici is much higher than it should be in the datasheet about 2uA.

I test it on P-NUCLEO-WB55 kit board which without any other devices connected on it with the official examples "PWR_STOP2_RTC" ,and I did test it as the readme.txt file tell me（remove all jumpers on JP5, and test the current on the JP2）, but the res...

I-Cube & B-L072Z-LRWAN1 : Strange behaviours on startup and running

Hi, I tried to play the I-Cube 1.3.1 / B-L072Z-LRWAN1 example in "End Node" mode but I noticed some strange behaviours. I leted the DUTY_CYCLE configured at 10 seconds and I'm playing on private network with Chirpstack Network Server and App Server. ...

I am using the CubeMX example UART_Hyperterminal_IT.ioc file to generate a IAR project to connect a P-Nucleo board to a PC running Hyperterminal. Is there code to add after you generate the project as i can't seem to get it to work? Any help appreciated.

CMWX1ZZABZ-091 in Sigfox mode

The reference design of the CMWX1ZZABZ-091 shows a connection between pins SX1276_DIO4 and PA5/ADC5/DAC2 when in Sigfox mode. The B-L072Z-LRWAN1 board has a jumper between these pins (SB26), but according to table 11 of the manual this jumper is Res...
