Hello, I have the following idea, but I am not really sure, if it can work as I imagine: we have one transmitter and several receivers. The goal would be to have syncronized timers/counters running on all receivers. Reading the FREQEST register, I find out how much the carrier frequencys differ from...

Re: SmartRF04EB

Take a look at the smartRF04EB schematic. You will find that the control signals for the EM boards (CC1100 and others all share common connector and pin-out) are available on P1 and P2 connectors. You'll want to jumper over from your MSP430 board to the CSn, SCLK, SI, SO pins on the EM connectors...

Try the following: Read back register AGCTEST (address 0x2B) when you receive the first packet. Write AGCCTRL0.AGC_FREEZE = 3 and then write the gain setting back to AGCTEST.

Re: sensitivity as function of preamble and sync word
Sverre
The preamble, which ideally is a 0-1 sequence, is used to set up the correct gain in the AGC, sets up the data deciscion slicing level, and does bit synchronization. If the preamble is too short there is not sufficient time for the RX path to be set up correctly before the real data starts coming in...

The register settings you get from SmartRF Studio are optimized for FSK/MSK and not OOK/ASK. Please refer to design note DN022 as this note tells you what registers to change when going from FSK to OOK and also a gives guidelines on how to find the optimum register settings for the AGC

Hi nick836, First to clarify the issue with the xtal running or not. The easiest way to check that it is running is to check the output on GDO0 after reset. It's default output is CLK_XOSC/192. To verify that the chip is ready, check GDO2 after reset. GDO2's default output after reset is the...

CC1100 and CC1101 are compatible. Not sure what the input power level (or output power and distance between the units) is in your case, but there are two extremes you should check out: is this a saturation issue (if the units are close)? Try with a lower output power level. is this a sensitivity...
