// Sample RFM69 sender/node sketch, with ACK and optional encryption // Sends periodic messages of increasing length to gateway (id=1) // It also looks for an onboard FLASH chip, if present // Library and code by Felix Rusu - felix@lowpowerlab.com // Get the RFM69 and SPIFlash library at: https://github.com/LowPowerLab/ // with RC522 attached,it's important to keep SS of RC522 high, so that we can clear the SPI interface and make RF working. // 2114/12/16 in Tr2 we will take out not used code, and transmit simple code, as well as receive // In try 2 it keep on retry 2 times, (which is totally 3 tramsmitions for the same thing), after changing the gateway code with highpower 69HW, // it works normally. /*2014/12/17 IN try3 I will first send out a RF message, then read RFID, then send out RFID 1st init RF, send a message through RF for testing,then stop RF, and init card reader, and read card ID, it works, but should we stop the interrupt IN try4, sent RF, read card, and send RF again, by changing SS high to keep the device out....it works. 2015/01/02 Not sure what was the diference between try4 and try 5, but with moteino, some times initialization is very long, or fail could it be an effect of SPI flash? 2015/01/03 to make a receive node from try 5 could easily hang, should be the time division between card reader and RF.when gate get ack, get get no card data, and sometimes, card reader does not read. So, adding following for interlock on SPI: digitalWrite(10, HIGH); digitalWrite(SS_PIN,LOW); not sure if need to re init card reader again try to init 522 every time after switch, it can read the card, almost every time, still some time fail. but don't understand what make note to sed out message */ #include #include #define NODEID 2 //unique for each node on same network #define NETWORKID 100 //the same on all nodes that talk to each other #define GATEWAYID 1 //Match frequency to the hardware version of the radio on your Moteino (uncomment one): #define FREQUENCY RF69_433MHZ #define ENCRYPTKEY "sampleEncryptKey" //exactly the same 16 characters/bytes on all nodes! #define IS_RFM69HW //uncomment only for RFM69HW!
