Arduino UNO + Dragino Lora Shield v1.4 can connect to TTN v2 but not on TTN v3 AU915

Hi,

I’m trying to connect the arduino to TTN v3 via ABP on AU915. On TTN v2, both ABP and OTAA work fine. But since now, v2 is read only, I need to setup end device on TTN v3.

My hardware is:
Arduino UNO with Dragino Lora Shield v1.4 AU915

Steps I’ve taken,

  • use LoraWAN version 1.0.2, 1.0.3
  • tick reset frame counter
  • add RX1 Delay 1s with 0 offset
  • RX2 data rate 8 with freq 923300000

But still, I couldn’t received the output in TTN.

The serial monitor seems fine.

Starting
09:54:15.994 -> 8615: EV_TXSTART
09:54:15.994 -> Packet queued for frequency (Hz): 917600000
09:54:18.091 -> 139843: EV_TXCOMPLETE (includes waiting for RX windows)
09:55:18.096 -> 3890317: EV_TXSTART
09:55:18.096 -> Packet queued for frequency (Hz): 917400000
09:55:22.040 -> 4021552: EV_TXCOMPLETE (includes waiting for RX windows)
09:56:20.219 -> 7772029: EV_TXSTART
09:56:20.256 -> Packet queued for frequency (Hz): 917800000
09:56:22.349 -> 7903267: EV_TXCOMPLETE (includes waiting for RX windows)

Also, I don’t have access to gateway log, so I cannot check anything gateway side.

I’m using MCCI LowaWAN LMIC 4.0.0 library (GitHub - mcci-catena/arduino-lmic: LoraWAN-MAC-in-C library, adapted to run under the Arduino envi), with setting as follow:

lmic_project_config.h

// project-specific definitions
//#define CFG_eu868 1
//#define CFG_us915 1
#define CFG_au915 1
//#define CFG_as923 1

//#define CFG_kr920 1
//#define CFG_in866 1
#define CFG_sx1276_radio 1
//#define LMIC_USE_INTERRUPTS

#define LMIC_LORAWAN_SPEC_VERSION LMIC_LORAWAN_SPEC_VERSION_1_0_2
#define DISABLE_PING
#define DISABLE_BEACONS
#define LMIC_ENABLE_DeviceTimeReq 0

 * This example sends a valid LoRaWAN packet with payload "Hello,
 * world!", using frequency and encryption settings matching those of
 * the The Things Network.
 *
 * This uses ABP (Activation-by-personalisation), where a DevAddr and
 * Session keys are preconfigured (unlike OTAA, where a DevEUI and
 * application key is configured, while the DevAddr and session keys are
 * assigned/generated in the over-the-air-activation procedure).
 *
 * Note: LoRaWAN per sub-band duty-cycle limitation is enforced (1% in
 * g1, 0.1% in g2), but not the TTN fair usage policy (which is probably
 * violated by this sketch when left running for longer)!
 *
 * To use this sketch, first register your application and device with
 * the things network, to set or generate a DevAddr, NwkSKey and
 * AppSKey. Each device should have their own unique values for these
 * fields.
 *
 * Do not forget to define the radio type correctly in
 * arduino-lmic/project_config/lmic_project_config.h or from your BOARDS.txt.

hi, did you found any solution?

I’ve tested around different gateway and it works with the same configuration. Probably something wrong with first gateway I’ve tested with.
