Consider raising support questions on the forum first

There is a discussion site, forum.mcci.io, which includes a category focused on the Arduino LMIC. Unless you're sure that your problem is a bug in the LMIC, it would be great if you can try for help there first. That will keep issues focused on work that needs to be done by the developers.

Describe your question or issue

Please give a clear and concise description of the problem you're facing and what you'd like help with.

Environment

This information is very important; it's hard to help without a complete set of answers.

Hello

I am using lora shield v1.4 and arduino uno and au915 and using the ttn-otaa example The port monitoring only show EV_TXSTART EV_JOIN_TXCOMPLETE :no join accept And my applicant data in TTN is no data appear My gateway is self-build single channel using rasp pi and lora shield v1.4 and there are no data appear on gateway in TTN

my pin mapping is const lmic_pinmap lmic_pins = { .nss = 10, .rxtx = LMIC_UNUSED_PIN, .rst = 5, .dio = {2, 3, LMIC_UNUSED_PIN}, };

Any help will be grateful Thanks !

Hi,

Sorry you're having problems.

If you have two devices, please use the raw sketch to confirm radio tx/rx performance.

After that, try setting the clock error to a large tolerance, e.g. LMIC_setClockError(MAX_CLOCK_ERROR * 20 / 1000). Also, at the same time, in your project configuration file, add #define LMIC_ENABLE_arbitrary_clock_error 1. This often helps.

If not, please share your project config file and test sketch.

Best regards, --Terry

Thanks for your detailed and quick reply I am sorry I am very new in the Lora. After I put LMIC_setClockError(MAX_CLOCK_ERROR * 20 / 1000) before dosend() in ttn-otaa, and put #define LMIC_ENABLE_arbitrary_clock_error 1 in Arduino\libraries\arduino-lmic-master\project_config. I get this in my rasp pi terminal image However I still get EV_TXSTART EV_JOIN_TXCOMPLETE :no join accept in arduino port monitoring. image

my sketch code is

the rasp pi code is come from this link , which is compiled by sudo ./single-chanel-ptk-fwd very appreciate!

terrillmoore commented 2 years ago

A Join message is always sent at SF10. The "single channel gateway" is listening at SF7. This means that it won't hear the JoinRequest message (for non-gateway LoRa chips, the TX and RX SF must match (as must the frequency).

The LMIC can't easily be changed to use SF7 for JoinRequest, but perhaps the SingleChannel gateway software can be changed to always listen on SF10 rather than SF7.

Single channel gateways are very troublesome and are the very hardest way to get started with LoRa. I strongly suggest spending a little money (US $80) for a Things Network Indoor Gateway. Whoever introduced single-channel gateways did learners a great disservice, because it looks like an inexpensive way to start. But it also leads to frustration and gives a distorted view of the technology. (I'm not sure TTN really supports single-channel gateways, in fact.)

liuhengjing-sudo commented 2 years ago

Thanks for your reply After I put the gateway outdoor just the yard, the node is connected and send the uplink message slowly. However after I want retry this, there is loop in Applicant live data: Forward join accept message Accept join request

The port monitoring in arduino is still no join accept I try SF10 it does not work And I try the ttn ABP, with the DEVADRR NESKEY APPSKEY from this end device in Applicant which gives me failure message in port monitoring. I am still adjust the distance between gateway and the node, sometimes the applicant shoews that the joint sever failed, I am not sure what is the problem right now

But Thanks again!

After that, try setting the clock error to a large tolerance, e.g. LMIC_setClockError(MAX_CLOCK_ERROR * 20 / 1000). Also, at the same time, in your project configuration file, add #define LMIC_ENABLE_arbitrary_clock_error 1. This often helps.

Thanks for this @terrillmoore. My devices didn't want to join on SF7, even though I had a gateway very close. Adding the clock error compensation allowed them to join at the first try.

OK guys, I had the same problem, so let me tell you how I fixed it : I went to lmic.project.config , and there I disabled all the region settings and just left #define LMIC_ENABLE_arbitrary_clock_error 1 and #define CFG_sx1276_radio 1 , then you go to your basic settings .ini file -> in my case is platformio.ini and there you must add your region like this :

build_flags = -D CFG_eu868=1

This worked for me, let's hope it will help somebody too. :)
