Hi @SedCore,
I think this issue is related the change of the STSAFE-A power management on B-U585-IOT2A board.
The error reported (1) is STSAFEA_COMMUNICATION_ERROR which generally occurs on the first STSAFE-A commands when the STSAFE-A is not responding on the I2C.
According to the User Manual of the B-U585-IOT2A board, the PF11 pin shall be 0 to enable the STSAFE-A.
In the X-CUBE-IOTA v3.0.0 x-cube-iota1/Projects/B-U585I-IOT02A/Applications/IOTA-Client/NetXDuo/App/STSAFE/stsafea_service_interface.c
in the HW_IO_Init, you have this line which set the PF11 to 1 :
HAL_GPIO_WritePin(STSAFEA_VREG_GPIO_PORT, STSAFEA_VREG_PIN, GPIO_PIN_SET);
Therefore, this disabled the STSAFE-A.
if you replace the line by HAL_GPIO_WritePin(STSAFEA_VREG_GPIO_PORT, STSAFEA_VREG_PIN, GPIO_PIN_RESET);
It should enable the STSAFE-A and you should be able to run the test code.
Best Regards,
Benjamin
