Industrial IoT Long Range Wireless pH and Temperature Sensor - Custom Firmware Help

Hi,
I currently have this sensor in which the minimum transmission intervals is 2 minutes, but the city requires us to have a 1 minute transmission interval.

I saw in another post where you guys have discussed about custom firmware to change this minimum interval.

Also I might need help calibrating it. Do I have to use com operator to send packets to it, or could this also be done in node red?

The minimum interval supported by ph sensor is 30sec. you can set using node red.

for calibration we recommend USB modem

So we can disregard what’s written here?

we dont recommend setting it lower than 2min but it can be set.

I was able to successfully configure it to 1 min.

Ok as for calibration I have the ethernet modem. Is there any recommendations for this procedure: Wireless IoT ORP pH and Temperature Sensor Product Manual - NCD.io

I dont have the usb modem, so com operater probably wouldnt be able to used? How to procede then

alpha station can be used for calibration as well.

Im having a problem with alpha station.
The MAC address of the PH sensor is shown, but all the other columns arent filled and the buttons look like that.

I think I might have an idea why. Let me try reconfiguring and find out.

Yeah, resetting the configuration fixed it. I can see the details now.

Ok, how do I use alpha station to transmit packets to the sensor? configuration mode doesnt do anything with calibration?

Never mind it does. I guess the old bugged thing messed it up
