CubCell is not receiving packets sent by Gateway

#1

I’ve 2 nodes one with sx1272 and another is CubeCell -ASR6501 with sx126x both are set on same frequency 865062500

by using util_tx_test gateway is sending 1000 packets to nodes

sx1272 is receiving the packets but sx126x(CubeCell -ASR6501) is not receiving a single packets sent by gateway

command is
./util_tx_test -r 1257 -f 865.0625 -m ‘LORA’ -s 7 -p 22dBm -k 1 -t 1000 -x 1000

anyone has observe this behavior? or know why this is happening?

What sketch have you uploaded to your cubecell?
Have you checked if the sync word is right?

#define TX_OUTPUT_POWER 20 // dBm

#define LORA_BANDWIDTH 0 // [0: 125 kHz,

#define LORA_SPREADING_FACTOR 7 // [SF7…SF12]
#define LORA_CODINGRATE 1 // [1: 4/5,

#define LORA_PREAMBLE_LENGTH 8 // Same for Tx and Rx
#define LORA_SYMBOL_TIMEOUT 5 // Symbols
#define LORA_FIX_LENGTH_PAYLOAD_ON false
#define LORA_IQ_INVERSION_ON false

{
Radio.SetRxConfig( MODEM_LORA, LORA_BANDWIDTH, LORA_SPREADING_FACTOR,
LORA_CODINGRATE, 0, LORA_PREAMBLE_LENGTH,
LORA_SYMBOL_TIMEOUT, LORA_FIX_LENGTH_PAYLOAD_ON,
0, true, 0, 0, LORA_IQ_INVERSION_ON, true );

Radio.Rx( 0 );
}

Also,

change sync word form private to public now cubecell is receiving the packets
thanks to point out
