hi
I have 2 NRF24 radios with antenna and 12 without. i have set up a serial gateway on a arduino UNO and a Humidity sensor on another UNO (also tried on Pro Mini) Yesterday i had this basic setup working using the two antenna version RF modules. i then substituted the rf modules for antenna less ones. in the serial monitor, both came up with " radio init fail ,so i swapped them back. now the Humidity sensor says "id req" it sort of sends to
gateway (i have no controller. just veiwing in ser monitor). i have capacitors on power lines. have reloaded sketches several times but still get the id req in the sensor side, i have even tried different sensor sketches they all sort of work, but give the id req thing. (also cleared eeprom)
I dont know whether it is connected but ALL 12 ! of the antenna less ones say "radio init fail" in both sensor and gateway, they were all new and had worked previosly.

i am trying to compile the ethernet gateway and when i first started was getting loads of "directory dosent exist" errors i fixed this by moving the mysensors library. following the IDE install instructions on the site the IDE installs to C:\Program Files (x86)\Arduino\arduino.exe (the Default). but the sketches folder where i put the my sensors library is in C:\Users\Chris\Documents\Arduino\libraries i have copied the libraries folder to both locations and have got past all the doesnt exist errors. but now i get the following compile error:
C:\Users\Chris\Documents\Arduino\ethGateway\ethGateway.ino: In function 'void output(const char*, ...)':
ethGateway:135: error: 'serialBuffer' was not declared in this scope
vsnprintf_P(serialBuffer, MAX_SEND_LENGTH, fmt, args);
exit status 1
'serialBuffer' was not declared in this scope

i have removed and re installed the arduino IDE and mysensors library several times but i get the same error every time ! i think it could be somthing to do with the directories been in the wrong place and duplicated all over. could someone please clarify the best place to put arduino IDE, The Libraries and the Sketches folder.
or point me in right direction to get rid of this error. i have edited the config file to enable soft SPI.
many thanks

Just figured it out .The gatewayutil.h file i was using was wrong, i copied and pasted the version off the codebender sketch (which is completely different to the one i had, dont know where it came from ??) but noticed line 25.....char serialBuffer[MAX_SEND_LENGTH];
sorted
