Data corruption when send SoftwareSerial data about espsoftwareserial HOT 6 CLOSED

I just find that it has already updated to disable interrupt in 9600 also.
Please refer to the commit 7077979

Old version:

m_highSpeed = speed > 9600;

New version:

m_intTxEnabled = speed < 9600;

Have you try the latest version already?

Anyone can help me about this?

I also encountered problem in 9600bps (with GPIO 14, 13), but it works fine in 115200bps.

I'm still studying if this is related to low speed communication, since the interrupt will be disabled during transmission only if m_highSpeed (m_highSpeed = speed > 9600;). i.e. the transmission can be interrupt for 9600bps. However, disable interrupt for low speed communication may have other impact as the transmission time is relatively long.

I'm not sure if it's really related to the interrupt setting, could you please try if your problem can be solve in other speed above 9600bps?

Hi,
Thank you for your advice.

So, I have test with same scenario by send out data with baud rate(14400, 19200, 28800, 38400, 56000, 57600 and 115200) every 100ms for 5 minutes, all of them work fine.

That's meaning the problem occurs only 9600bps.
I have no choice to use other baud rate due to my connection device is using 9600bps.

Previously, I installed SoftwareSerial from Arduino library manager, it provided SoftwareSerial v1.0.0 and cannot be upgrade.

I have to pull latest version from this git.
Currently it's working fine more than 10 mins.
I will test over the week and give feedback to you again.

Hi,
I have test over a month with my full program.
Serial communication is looking good.
Once a week, still found some problem but not sure it's related with corruption or not.
