Hi Felix ,
Thanks for your reply , can you direct me to a particular file where you have followed that sequence in your library .
HopeRF gave me an example and they are settiing these base parameters to configure RFM69 :
const word RFM69ConfigTbl[20] = {
0x0200, //RegDataModul : Packet Mode, FSK, No Shaping
0x0502, //RegFdevMsb 241*61Hz = 35KHz
0x0641, //RegFdevLsb
0x0334, //RegBitrateMsb 32MHz/0x3410 = 2.4kpbs
0x0410, //RegBitrateLsb
0x130F, //RegOcp Disable OCP
0x1888, //RegLNA 200R
0x1952, //RegRxBw RxBW 83KHz
0x2C00, //RegPreambleMsb
0x2D05, //RegPreambleLsb 5Byte Preamble
0x2E90, //enable Sync.Word 2+1=3bytes
0x2FAA, //0xAA SyncWord = aa2dd4
0x302D, //0x2D
0x31D4, //0xD4
0x3700, //RegPacketConfig1 Disable CRC£¬NRZ encode
0x3815, //RegPayloadLength 21bytes for length & Fixed length
0x3C95, //RegFiFoThresh
0x581B, //RegTestLna Normal sensitivity
//0x582D, //RegTestLna increase sensitivity with LNA (Note: consumption also increase!)
0x6F30, //RegTestDAGC Improved DAGC
//0x6F00, //RegTestDAGC Normal DAGC
0x0104, // RegOpMode = Standby
};
