Lora not joining #6

Closed netmonk closed 4 years ago

netmonk commented 4 years ago

I freshly installed an compiled this code on my Tbeam rev10 (latest). I already run on this device paxcounter with success to join lora TTN. I run also the GW, so i can see what message are transiting from it.

I put the appeui lsb, deveui lsb and appkey msb, i cannot see any join in the gateway. This is for EU version standard payload.

first, the LED_PIN is set to 14, but it is also the Gpio for lora RST on rev10 so i i changed it to unused GPIO, but still nothing goes out from the board. Also if you look at the datasheet, rev10 only DIO0, and DIO1 and DIO2 are not defined. So tried to change them to LMIC_UNUSED_PIN in ttn.ino but no success.

first attempt to correct the pinout

I just got the rev10 board, but I haven't had a chance to plug it in and mess with it. Let me know if you find or fix anything in your investigation.

maybe you take a look here ;-)

if not set to single channel gateway, LMIC_startJoining() will never be executed.

_LMICstartJoining(); should be before _#ifdef SINGLE_CHANNELGATEWAY.

ttn.ino

#elif defined(USE_OTAA)

  #ifdef SINGLE_CHANNEL_GATEWAY
  // Make LMiC initialize the default channels, choose a channel, and
  // schedule the OTAA join
  LMIC_startJoining();

  // LMiC will already have decided to send on one of the 3 default
  // channels; ensure it uses the one we want
  LMIC.txChnl = SINGLE_CHANNEL_GATEWAY;
  #endif
#endif

Thanks for the info. I'm going to try to get back into this in 2 weeks when I have more time and try to test and incorporate changes.
