Hi guys,
I have the same setup ic880A-spi with raspberry pi 2 and I can't get any packet. The packet forwarder is started successfully as I see in /var/log/daemon.log
When I start the tx test, it doesn't receive anything
./util_tx_test -f 868
INFO: 1 pkts @868.000000 MHz (BW 125 kHz, SF10, 20B payload) 14 dBm, 1000 ms between each
INFO: waiting to receive a PULL_DATA request on port 1782
On the concentrator side, I see that there are few packets but with bad CRC. They are consequently ignored :

[UPSTREAM]
RF packets received by concentrator: 1
CRC_OK: 0.00%, CRC_FAIL: 100.00%, NO_CRC: 0.00%
RF packets forwarded: 0 (0 bytes)
PUSH_DATA datagrams sent: 1 (230 bytes)
PUSH_DATA acknowledged: 0.00%
[DOWNSTREAM]
PULL_DATA sent: 3 (0.00% acknowledged)
PULL_RESP(onse) datagrams received: 0 (0 bytes)
RF packets sent to concentrator: 0 (0 bytes)
TX errors: 0
[GPS]
Invalid gps time reference (age: 1456735916 sec)
END
How can I check that the hardware is working fine? The power led is on but the other leds aren't blinking
What is really strange in my setup, if I send RF packets (from a USB end node that can send basic RF packets or Lorawan packets), things are better:

I am really confused. Can you please help me in finding what's wrong?
