How can I set the reconnect time interval? #30

I have been working on a project by this awesome jsmodbus, but when I enable the AutoReconnect, program will do the reconnect high-frequency, even raise the CPU utility to 100 %. So I want to know is there any function I can call to set the reconnect time? Thanks

Normally establishing a connection through TCP/IP takes some time to fail. What I am curious about is why is the connection not established so fast. Can you post some code and maybe some debug messages ( set the logEnable to true and the logLevel to debug).

Sorry about my late reply. I was trying to complete a node-red module with reconnect feature by jsmodbus. I had seen one but without reconnect feature. I try to create some situation like un-plug the cable or something, like server off-power for like an hour. so If the reconnect is keep trying too fast, it seems like too much work for a gateway. So I'd like to know is there any way to slow the reconnect time?

Thanks

One way would be to set the autoReconnect attribute to false and listen for the close event and manually reconnect.


client.on('close', function () {

    setTimeout(client.connect, 5000);

});
