Hi everyone,
Hope you all are doing fine in this tough times.
We were using BG95-M3 module in one of our project which was working fine till now.
But in one of our hardware (one in thousands) we were experiencing lot of noise on the RI (Ring indicator) pin, to tackle this issue we implemented the de-bounce delay.
Below image is the screenshot of the noise captured on DSS.
But the real problem is that when we receive the actual interrupt (120 msec) upon receiving SMS, that interrupt itself is filled with noise peaks.
Now this behavior is making it hard to differentiate the noise and actual interrupt.
Can anyone guide us to the proper direction to tackle the noise or what may be the root cause of this noise.
Thanks in advance for your precious time.
