How to change the RFM69 Modem configuration?

[Gibber]

I would like to try a lower transmission rate on my RFM69 radios. At the moment I only have one gateway and one sensor.
I tried uncommenting line 801 of Myconfig.h and changing it to #define MY_RFM69_MODEM_CONFIGURATION (RFM69_FSK_BR9_6_FD19_2)
I then reloaded the code for the serial gateway to my gateway node and the code to my sensor node as well.
After the change I was unable to get the sensor to connect. I got repeated TSM:FPAR:NO REPLY.
Am I missing a step here? Is there any reason this would not change the bit rate as desired?
As soon as I commented out line 810 and reloaded the code to both nodes connection was restored.

Hi,

need to be used without brackets (see this post) :

#define MY_RFM69_MODEM_CONFIGURATION RFM69_FSK_BR9_6_FD19_2

Do not modify MyConfig.h. Put it into the sketch for your node (somewhere before line: #include <MySensors.h>).

Working great! Thanks very much!
