I need help with LMIC and TTN. In my paxcounter project i ran into a problem which won’t fix , resulting in paxcounter software is currently unusable with TTN. With current version 3.0.99.x of MCCI LMIC joins stuck in a loop with join requests. This is not a hardware / device dependent problem. Sa…

First, you need to try to figure out: Is no join accept transmitted? Or Is the join accept transmitted but not received ? [image] Verkehrsrot: Sometimes joins are succesful after a couple of minutes, when LMIC has climbed on higher SF levels. Or when it has walked, one number at a time,…

Yes, I don’t see join accept messages on the gateway console, but what if TTN backend sent them to another gateway? I already thought on a DevNonce problem, too. To verify this, i created a new device with fresh keys. Same problem.

Update: Looks like there are two stacked issues. During testing i accidently changed an AppKey. This explains why the backend did not answer the join request: just because wrong key. But now i am back to the original issue. Join request and join accept are shown on the gateway. But the device with …

[image] Verkehrsrot: But now i am back to the original issue. Join request and join accept are shown on the gateway. But the device with the MCCI LMIC OTAA compliance script does not join reliably. The timing situation on the ESP32 Arduino platform looks nasty, and I’m not sure it’s truly res…

Thanks for this cooking receipt. I will try to get a timing measurement reference setup. Do you have any suggestions how to increase realtime behaviour of arduino-esp32 core, i.e. switch off / deactivate certain components which cause jitter?

[image] Verkehrsrot: Do you have any suggestions how to increase realtime behaviour of arduino-esp32 core Program the ESP32 natively without Arduino, or if you have to stay with Arduino switch to a platform like ESP8266, STM32, or SAMD where the Arduino core is more reasonable, debugged, and …

I would prefer native ESP32 IDF, but did not find a native ESP32 LMIC port yet.

It’s not really a big deal to de-Arduino-ify a current LMiC repo; the code itself wasn’t originally intended for Arduino at all, mostly what you have to do is turn the silly debug print functions back into something normal (but there aren’t that many to begin with, since they are CPP methods and mos…

[image] Verkehrsrot: I would prefer native ESP32 IDF, but did not find a native ESP32 LMIC port yet. ttn-esp32 is a port of LMIC to ESP-IDF. The lmic-early-v3 branch even integrates the latest MCCI LMIC development. It has an entirely ESP-IDF specific hardware abstraction layer (HAL) and mos…

As the ESP32 Arduino Core runs on top of the ESP32 IDF, would it be possible to use ttn-esp32 with ESP32 Arduino Core to get a better LMIC implementation for Arduino on ESP32?
