OTA, Application Read Protection and PCROP
Hi, I have a project where I need to read protect my application code. The problem with RDP is that it would erase the entire flash (including OTA). I assume this problem is to be solved by using PCROP on the OTA code. I have attempted to protect the...
Connecting B-L072Z-LRWAN1 to TTN with lora i-cube_irwan endnote gives status never seen
While connecting the B-L072Z-LRWAN1 to TTN with lora i-cube_irwan endnote and changing the AppEui and Appkey gives a never seen status at TTN. Putty perfectely shows the Version, OTAA, devEui, AppEui and AppKey but does not show the join. How can i...
Adding PWM function in existing Ping Pong example
Hi,I have generated the code for PWM generation using STM32 CubeMX and it is working fine on B-l072Z-lrwan1.But when I was trying to integrate same code with the existing Ping Pong example, I was not getting any PWM signal on respective pin. I have a...
What are the benefits of using STSAFE security IC to reset a microcontroller?
I am using BL072Z board and the datasheet says:8.6 Reset sourcesThe reset signal of the B-L072Z-LRWAN1 Discovery kit is active low and the reset sources is one of the following:• Reset button B2• Arduino Uno V3 shield board from CN4• LoRa®/Sigfox™ mo...

Resolved! How in-accuracy of SYSCLK affects the HAL_GetTick?
I have observed, using a frequency counter, that the HSE clock on Nucleo board (after using the calibration value in the OTP memory) is off by around 20ppm. I have configured the SYSCLK to HSE_SYS. Now, HAL_GetTick counts the tick from the derived c...
