Problems with communication from Arduino device to Pi gateway

[emilvi]

Thank you for this really impressive software and documentation

I have set up a Pi3 with your image, and configured the setup. I also have a Ardiuno Uno. Both are set up with new inAir9B. I have have set up PABOOST on and off, and different LORAMODE (1,2,and 3)

Here is the output from both Pi and Ardiuno which seems OK for me. I had problems with compiling Ardiuno_lora_temp, but after delete sx1272.h and let it use the files in the library it worked OK (I have also testet with copying the library files to the same folder, and It compiled OK.) but no connections between devices. I have also changed the library Arduino AVR boards to 1.6.11

I have followed the cabling from both video on Youtube and documents, and it seems OK

Any suggestions?

Sorry I have mistaken the inAir9 module, what I have is inAir9 (not 9B which I tought), but still I have problems. I have commented out the PABOOST in arduino, and changed the radio.makefile file. Is there any other settings that have to be set?

_pi@raspberrypi:~/lora_gateway $ cat radio.makefile

options are: -DPABOOST -DMAX_DBM=v

CFLAGS=-DMAXDBM=14

I still have problems with sending I wonder what the RSSI=125 means

--> RSSI -125 Sending Ping

and output from raspberry

Hi, sorry to ask, but did you recompile after changing the radio.mkefile, then reboot?

[emilvi]

Yes I have recompiled, with same result I have ordered new inAir9 to check if there is any HW problems. And also new boards

[emilvi]

It seems that when connecting inAir9 VSWITCH (VS) to 3.3 V on the Arduino it worked right away. Should the VS be connected to any other pin instead of 3.3V?

[CongducPham]

Strange, I never use this pin.
