Good product but a few changes needed in your code.
If you've used the RYLR998 modules, be aware that the RYLR993 will require a few changes to get it to work with the other modules. First of all, these come setup for 9600 baud by default, where the 998 was 115600. Second you need to set it to proprietary mode then reset it. The proprietary mode commands are at the end of the AT command document. Third, the syntax has changed so be ready to change the code you used with the 998. I'm looking forward to some range testing.

Excellent Range, Easy to use!
I love this product since it is very east to use for projects using ANY micro processor. As long as you can provide 3.3v, GND, TX, RX, you are good to go! I have been using this device to monitor my boat which is docked about a mile and 1/2 away. I can track Temperature, Humidity, Location, and motion. For this long distance use case it works flawlessly! I am trying to now take advantage of the Helium network capability but running into a few issues. Here is the script I am using and of course have changed my digits in the script for privacy: BEGIN configuration ->ATZ -----REYAX RYLR993 FREQ:915000000 +READY ->AT OK ->AT+VL=3 OK ->AT+BAND=? +BAND=915000000 OK ->AT OK ->AT+BAND=0 AT_PARAM_ERROR ->AT+DEUI=60:81:F9:D6:11:22:33:44 AT_ERROR ->AT+APPEUI=60:81:F9:6B:11:22:33:44 AT_ERROR ->AT+NWKKEY=42:6D:7A:D9:12:2E:11:22:33:44:55:66:77:88:99:00 AT_ERROR

How to fix
Please if you have any trouble with it hold down the reset button for like 10 seconds it fixed it for me.

It failed after a week of use
I've attached to orangePi and keep the connection a week long then both units failed independently. It is not usable and outside of return period. Waste of money.

I used these in proprietary mode, and they worked great.
Worked as advertised

Works great!
At first, I wasn't crazy about using UART (Would have wanted I2C) but once I worked out the state machine I needed to work with bi-directional serial comms, it is very dependable and performs well.
