   * a ready BeagleBone Black equipped with the CC1200
-  * one TI Development Kit for the CC1200
+  * another BeagleBone Block equipped with the CC1200
-  * Smart RF Studio.
+  * 4C.
+===== Tasks  =====
+  * connect the first BeagleBone Black to your computer and install, execute 4C.
+  * open TX Synchronous Serial Mode in test window.
+  * export all registers to a file.
+  * connect the BeagleBone Black to your computer and login as superuser.
+  * copy the export file from 4C to the BeagleBone Black.
+  * import the export file into your program and initialize the registers according the values of the export file.
+  * Read chapter 6.9 about the RSSI of the [[http://www.ti.com/lit/ug/swru346b/swru346b.pdf?ts=1588225642109|CC1200 Users Guide]] and implement it.
+  * if the program is correctly compiled and linked start it.
+  * If this is the case bring 4C in “Continuous RX” mode and start the transmitter. At 4C the RSSI should increase. If switching off the transmitter, the RSSI should drop down.
+===== Remarks  =====
+  * Your transmitter will insert a sync-word for better bit synchronization. Try to figure out, what sync word will be used.
+  * Figure out, the use of the GPIO lines (what functions have the lines).
