I am sending 'Hello mitcoe' message from file source as well as socket using USRP B200 hardware
Parameters :
Frequency: 868MHz
SF: 8
Code rate: 4
BW: 250KHz
Sampling Rate: 250 KHz
Header: True
and i want to receive this on Pycom LoPy LoRa node.
same parameters on LoPy LoRa node.
But i receive on LoPy LoRa some things like this
Received data:
1 b'\xe7\xe7+\xfa\x00MB'
2 ��+�MB
3 b'e7e72bfa004d42'
Rx_cnt:1
(rx_timestamp=676924426, rssi=-98, snr=0.0, sfrx=8, sftx=0, tx_trials=0)
Received data:
1 b'\xe7\xe7\xeb\xfa\x00MB'
2 ����MB
3 b'e7e7ebfa004d42'
Rx_cnt:2
(rx_timestamp=677851000, rssi=-98, snr=0.0, sfrx=8, sftx=0, tx_trials=0)
My LoPy code to receive data is:
print("In Receive Mode")
s.setblocking(False)
while True:
data = s.recv(64)
if(data):
print("Received data: "+"\n1",data)
print ("2",data.decode('utf-8'))
print("3",binascii.hexlify(data))
i+=1
rx2tx_data = 'Rx_cnt:'+str(i)
print(rx2tx_data)
print(lora.stats())
I am not able to receive correct data.
Also i am sending message multiple times but lora only receives twice or thrice.
