Other Parts Discussed in Thread: CC1100, CC1150, CC1101
Hello,
I use RF Studio 7 to set the registers for lower data rate and RX BW. I have working setting for a long time for CC1100 RF chip, 250kbps, 540KHz, MSK, 433.92MHz.
I noticed kind of not accurate tool performance, when basing on one typical setting and changing the data rate and BW will cause only MDMCFG4 to be changed. But when basing on other typical setting and changing the parameters will cause additional to MDMCFG4 registers changes like: FSCTRL1, FOCCFG, BSCFG, AGCCTRL2, AGCCTRL1, AGCCTRL0, FREND1, FSCAL3.
I looked on CC1100 datasheet to validate those changes, but still doesn't make sense since if reducing data rate why AGC setting should be reduced, like LNA gain is reduced from maximum settings. And don't understand why other registers are affected as well ?
Both options to set the tool don't lead to desire performance, changing only MDMCFG4 showed worse performance for 125kb/270KHz than 250kbps/540KHz. And when changed other registers as well according to the tool, still don't see much improvement.
So, what's the best method to work with the tool? to use ccdebuger?
