Hi,
I am currently working with an STM32L452 as the master MCU, responsible for controlling a BlueNRG M2SP SoC, which is flashed with DTM_spi.hex.
During the course of conducting EMC tests on my device, I encountered an issue with ESD immunity testing. It appears that the main MCU gets stuck because it loses connection with the BlueNRG SoC under these test conditions. As a result, I am seeking assistance in finding a solution that enables the master MCU to detect disconnection events. With this capability, I aim to promptly reconnect both MCUs and ensure uninterrupted operation.
If anyone has experience with a reliable disconnection detection mechanism or any insights on addressing this concern, your guidance would be highly appreciated.
Note: I'm using the BlueNRG2 middleware generated by CubeMX.
Regards,
