Hello everybody,
currently I am setting up Chirpstack in Kubernetes.
For development purposes I use a Sparkfun 1CH Gateway that is equipped with the things4u Gateway OS. So far I have been able to connect the gateway with Chirpstack.
Now I tried to connect an Adafruit Feather M0 LoRa using the MCCI LoRaWAN LMIC Library with ABP but I have not been successful so far.
In the serial monitor I see that the device is queuing the packages:
22:26:09.519 -> 93306977: EV_TXSTART
22:26:09.679 -> Packet queued
22:26:11.645 -> 93437956: EV_TXCOMPLETE (includes waiting for RX windows)
The packages seem to never arrive in Chirpstack, the device I added has never been seen according to the device overview.
Is there a sample available on how to add the Device Adress, Network Session Key and Application Session Key in the ttn-abp-sample of the LMIC-library?
Could it be that I entered them in the wrong manner (all MSB)?
Example of how I currently added the constants in the ttn-abp-example:
// LoRaWAN NwkSKey, network session key
// This should be in big-endian (aka msb).
static const PROGMEM u1_t NWKSKEY[16] = { 0xF9, 0XE2, 0x5D, 0x09, 0x8F, 0x04, 0x21, 0x89, 0x77, 0x19, 0x79, 0xDF, 0XA3, 0x81, 0x3B, 0XB7 };
// LoRaWAN AppSKey, application session key
// This should also be in big-endian (aka msb).
static const u1_t PROGMEM APPSKEY[16] = { 0x15, 0xB7, 0xFD, 0xE7, 0xDC, 0x74, 0x53, 0x83, 0x04, 0xBB, 0xCB, 0x0B, 0xD4, 0xC7, 0xA1, 0xFD };
// LoRaWAN end-device address (DevAddr)
// See http://thethingsnetwork.org/wiki/AddressSpace
// The library converts the address to network byte order as needed, so this should be in big-endian (aka msb) too.
static const u4_t DEVADDR = 0x004F4824;
Any help is appreciated 
Best regards,
Dennis
