Basic RYLR890/896 test circuit not working

@kevinjones ..Indeed..see, we have more in common than we realized...lol

  I retired from from a paper mill in 2014 after 28 years.. but i was in industrial instrumentation for over 40 years..tuned several thousand PID loops over that time, and I have a very good understanding of how it works, and how to implement it. Writing the software is the challenge.. I'm just now learning C++, so I have a ways to go in making it work on my Arduino Uno..The robot is working in the various modes it was constructed to to from the kit I bought..It has follow the light, object avoidance( utilizing IR and ultrasonic sensors), RC control via an Ir controller, and can be operated through an app on my smart phone.. I'm in no hurry, Since I'm retired, everyday is a Saturday...lol

@inst-tech 

There was a whole thread some time ago in which PID was a topic.

@robotbuilder Thanks for the heads up.. I'll be checking out the link you provided..

kind regards,

Just an update on the 127x modules.  I mentioned 2 of them:

The cheaper "127x module":

and the "RA-02" model including .10 pitch breakout board:

I have found that the RA-02 device performs *much* better than the plain 127x module.  I get about 6x the distance (with the RA-02, well over 800 ft in my situation, from inside my house, through trees and other obstacles; only 150 ft with the cheaper module.)  I am using this antenna with IPEX connector with the RA-02:

DollaTek 433MHz Wireless 3dBi IPEX WiFi Spring Antenna for Ra-02 Module Lora OLED Board - 5pcs

Both modules use the 127x chip; perhaps the shielding on the RA-02 is a factor.  The RA-02 with the .10 pitch breakout board is also much more convenient for breadboarding as well final PCB build.

@kevinjones None of us can 'see' your amazon link, enclose the link in " " it's a forum bug. I would have assumed the reverse to be true based on the labelling until I noticed the external antenna.
