cdupaty	0:d974bcee4f69	33	* June, 22th, 2017
cdupaty	0:d974bcee4f69	34	* - setPowerDBM(uint8_t dbm) calls setPower('X') when dbm is set to 20
cdupaty	0:d974bcee4f69	35	* Apr, 21th, 2017
cdupaty	0:d974bcee4f69	36	* - change the way timeout are detected: exitTime=millis()+(unsigned long)wait; then millis() < exitTime;
cdupaty	0:d974bcee4f69	37	* Mar, 26th, 2017
cdupaty	0:d974bcee4f69	38	* - insert delay(100) before setting radio module to sleep mode. Remove unstability issue
cdupaty	0:d974bcee4f69	39	* - (proposed by escyes - https://github.com/CongducPham/LowCostLoRaGw/issues/53#issuecomment-289237532)
cdupaty	0:d974bcee4f69	40	* Jan, 11th, 2017
cdupaty	0:d974bcee4f69	41	* - fix bug in getRSSIpacket() when SNR < 0 thanks to John Rohde from Aarhus University
cdupaty	0:d974bcee4f69	42	* Dec, 17th, 2016
cdupaty	0:d974bcee4f69	43	* - fix bug making -DPABOOST in radio.makefile inoperant
cdupaty	0:d974bcee4f69	44	* Dec, 1st, 2016
cdupaty	0:d974bcee4f69	45	* - add RSSI computation while performing CAD with doCAD()
cdupaty	0:d974bcee4f69	46	* - WARNING: the SX1272 lib for gateway (Raspberry) does not have this functionality
cdupaty	0:d974bcee4f69	47	* Nov, 26th, 2016
cdupaty	0:d974bcee4f69	48	* - add preliminary support for ToA limitation
cdupaty	0:d974bcee4f69	49	* - when in "production" mode, uncomment #define LIMIT_TOA
cdupaty	0:d974bcee4f69	50	* Nov, 16th, 2016
cdupaty	0:d974bcee4f69	51	* - provide better power management mechanisms
cdupaty	0:d974bcee4f69	52	* - manage PA_BOOST and dBm setting
cdupaty	0:d974bcee4f69	53	* Jan, 23rd, 2016
cdupaty	0:d974bcee4f69	54	* - the packet format at transmission does not use the original Libelium format anymore
cdupaty	0:d974bcee4f69	55	* * the retry field is removed therefore all operations using retry will probably not work well, not tested though
cdupaty	0:d974bcee4f69	56	* - therefore DO NOT use sendPacketTimeoutACKRetries()
cdupaty	0:d974bcee4f69	57	* - the reason is that we do not want to have a reserved byte after the payload
cdupaty	0:d974bcee4f69	58	* * the length field is removed because it is much better to get the packet length at the reception side
cdupaty	0:d974bcee4f69	59	* * after the dst field, we inserted a packet type field to better identify the packet type: DATA, ACK, encryption, app key,...
cdupaty	0:d974bcee4f69	60	* - the format is now dst(1B) ptype(1B) src(1B) seq(1B) payload(xB)
cdupaty	0:d974bcee4f69	61	* - ptype is decomposed in 2 parts type(4bits) flags(4bits)
cdupaty	0:d974bcee4f69	62	* - type can take current value of DATA=0001 and ACK=0010
cdupaty	0:d974bcee4f69	63	* - the flags are from left to right: ack_requested\|encrypted\|with_appkey\|is_binary
cdupaty	0:d974bcee4f69	64	* - ptype can be set with setPacketType(), see constant defined in SX1272.h
cdupaty	0:d974bcee4f69	65	* - the header length is then 4 instead of 5
cdupaty	0:d974bcee4f69	66	* Jan, 16th, 2016
cdupaty	0:d974bcee4f69	67	* - add support for SX1276, automatic detect
cdupaty	0:d974bcee4f69	68	* - add LF/HF calibaration copied from LoRaMAC-Node. Don't know if it is really necessary though
cdupaty	0:d974bcee4f69	69	* - change various radio settings
cdupaty	0:d974bcee4f69	70	* Dec, 10th, 2015
cdupaty	0:d974bcee4f69	71	* - add SyncWord for test with simple LoRaWAN
cdupaty	0:d974bcee4f69	72	* - add mode 11 that have BW=125, CR=4/5, SF=7 on channel 868.1MHz
cdupaty	0:d974bcee4f69	73	* - use following in your code if (loraMode==11) { e = sx1272.setChannel(CH_18_868); }
cdupaty	0:d974bcee4f69	74	* Nov, 13th, 2015
cdupaty	0:d974bcee4f69	75	* - add CarrierSense() to perform some Listen Before Talk procedure
cdupaty	0:d974bcee4f69	76	* - add dynamic ACK suport
cdupaty	0:d974bcee4f69	77	* - compile with W_REQUESTED_ACK, retry field is used to indicate at the receiver
cdupaty	0:d974bcee4f69	78	* that an ACK should be sent
cdupaty	0:d974bcee4f69	79	* - receiveWithTimeout() has been modified to send an ACK if retry is 1
cdupaty	0:d974bcee4f69	80	* - at sender side, sendPacketTimeoutACK() has been modified to indicate
cdupaty	0:d974bcee4f69	81	* whether retry should be set to 1 or not in setPacket()
cdupaty	0:d974bcee4f69	82	* - receiver should always use receiveWithTimeout() while sender decides to use
cdupaty	0:d974bcee4f69	83	* sendPacketTimeout() or sendPacketTimeoutACK()
cdupaty	0:d974bcee4f69	84	* Jun, 2015
cdupaty	0:d974bcee4f69	85	* - Add time on air computation and CAD features
