(Pull request #10)SRV_MAC_NEW_CHANNEL_REQ (Pull request #7)SRV_MAC_NEW_CHANNEL_REQ command (Pull request #5)for loop indexes were wrong. (Pull request #4)Corrected the Port 0 MAC commands decryption
Changed the way the upper layer is notified. Now it is only notified when all the operations are finished
When a ClassA Tx cycle starts a timer is launched to check every second if everything is finished
Added a new parameter to LoRaMacEventFlags structure that indicates on which Rx window the data has been received
Added a new parameter to LoRaMacEventFlags structure that indicates if there is applicative data on the received payload
Corrected ADR MAC command behavior
DutyCycle enforcement implementation (EU868 PHY only)
REMARK 1 The regulatory duty cycle enforcement is enabled by default which means that for lower data rates the
node may not transmit a new frame as quickly as requested
The formula used to compute the node idle time is
Toff = TimeOnAir / DutyCycle - TxTimeOnAir
Example:
A device just transmitted a 0.5 s long frame on one default channel
This channel is in a sub-band allowing 1% duty-cycle. Therefore this whole sub-band (868 MHz - 868.6 MHz) will be
unavailable for 49.5 s.
REMARK 2 The duty cycle enforcement can be disabled for test purposes by calling the LoRaMacSetDutyCycleOn
function with false parameter.
Implemented aggregated duty cycle management
Added a function to create new channels
Implemented the missing features on the JoinAccept MAC command

(barometric) (gps)
Implemented an application LED control
If the server sends on port 1 an application payload of one byte with the following contents:
0: LED off
1: LED on
The node transmits periodically on port 1 the LED status on 1st byte and the message "Hello World!!!!" the array looks lik
{ 0, 'H', 'e', 'l', 'l', 'o', ' ', 'W', 'o', 'r', 'l', 'd', '!', '!', '!', '!' }
