The default parameters are 11 434.665MHz / DR0 (SF12, 125kHz) 12 2.4.8 EU433 Default Settings 13 The following parameters are recommended values for the EU433band. 14 RECEIVE_DELAY1 1 s 15 RECEIVE_DELAY2 2 s (must be RECEIVE_DELAY1 + 1s) 16 JOIN_ACCEPT_DELAY1 5 s 17 JOIN_ACCEPT_DELAY2 6 s 18 MAX_FCNT_GAP 16384 19 ADR_ACK_LIMIT 64 20 ADR_ACK_DELAY 32 21 ACK_TIMEOUT 2 +/- 1 s (random delay between 1 and 3 seconds) 22 23 If the actual parameter values implemented in the end-device are different from those default 24 values (for example the end-device uses a longer RECEIVE_DELAY1 & 2 latency) , those 25 parameters must be communicated to the network server using an out-of-band channel 26 during the end-device commissioning process. The network server may not accept 27 parameters different from those default values. 28 29 30 31 32
