Hi,
compiling arduino code without any modification for lecture 7, i got the following error:

Arduino : 1.8.13 (Windows 10), Carte : "Arduino Uno"

C:\Users\admin\Desktop\ERA\SDR\URCmaterialsV1.0\Scripts\Scripts\Lectures 7&8\Arduino\CC1101_configurable\cc1101_configurable.ino: In function 'void loop()':

^

Please help
Thank you

Dear CN8ZE,
please try to change line 40 of cc1101_configurable to:

Code: Select all

sprintf((char *) pckt.data, "This is message number: %03d\n", ++counter);

and line 41 to:

Code: Select all

int len = strlen((char *) pckt.data);

We cannot reproduce the problem, even though we have the same version of the Arduino IDE, but this edit should fix the problem and will be included in future releases
