NRF905 for 866Mhz and 867Mhz and lower data rate

[Wonderful IOT]

Hi,

In 868 Mhz band NRF905 supports frequencies 862.8Mhz, 868.2Mhz, 868.4Mhz and 868.8Mhz. The datasheet shows mapping of those frequencies to CH_NO.

In India only 865Mhz, 866Mhz and 867Mhz are legal, others are illegal. It looks like it should be possible to use these frequencies by changing CH_NO.

1. Can you let me know, the CH_NO mapping for these India specific frequencies please ?
2. Is it possible to lower the data rate to get better sensitivity than -110dBm@50kbps?

Thanks and Regards, Wonderful IOT

1. The formula to calculate the frequency is stated in chapter 11.7 in the Product specification. For 865 it should be 01100101, 866 = 01101010 and 867 = 01101111. But please calculate this again yourself to be sure.

2. No
