We’ve bought a LAUNCHXL CC13-90 EU Rev 1.2.0 & FW Rev 1.0
We uploaded the firmware Serial_CC13xx_Collector_T2.hex on the launchpad .
We have done several test using this launchpad , and it work well.
Now we’ve tried to work with external antenna .
So we removed the A2 component and added the 0 ohm resistor for R158 as asked on the page 2 of the attached file.
Without connecting the Antenna on the SMA connector, the connection using the launchpad is succeed !
To confirm this behaviour , we have removed A2 component on a second LAUNCHXL CC13-90 Without adding the 0 ohm resistor.
We’ve got the same result.
Is this a normal behaviour of the board to connect even all Antenna is disconnected?
Is there any method to disactivate it?
