5 years ago Just one more testing: If I compile and flash the code into "TTGO T_BEAM" it works. I have just problems with the "HELTEC LoRa 32 v.2."

5 years ago I saw this with other boards, too. Not sure if this an LMiC stack related issue. Could be a timing issue which is related to run the LMiC stack in multitasking environment of paxcounter. Could be a hardware issue related to wiring / signalling of DIO1 line to GPIO port of ESP32.
Can you please try this and report results here: Trial No. 1: Use current version 1.9.x from development branch. In this version i made significant changes to the multitasking which will affect timing in LMiC stack. Please report if you see a difference in join behaviour.
Trial No. 2: in lmic_config.h change line
#define CLOCK_ERROR_PROCENTAGE 5
to value 7

* This example sends a valid LoRaWAN packet with payload "Hello,

*
* This uses OTAA (Over-the-air activation), where where a DevEUI and
* application key is configured, which are used in an over-the-air
* activation procedure where a DevAddr and session keys are
* assigned/generated for use with all further communication.
*
* 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 an AppEUI, DevEUI and AppKey.
* Multiple devices can use the same AppEUI, but each device has its own

}Hallo cyberman, thanks for your answer, I will test your two trial mentioned above.

5 years ago I know the original LMiC library, but the MCCI fork is much better maintained and has lots of bug fixes.

5 years ago Trial No. 2: in lmic_config.h change line
#define CLOCK_ERROR_PROCENTAGE 7It works with the master code and the setting above ad hoc with my "HELTEC LorA 32 V2" It joins immediatelly.

5 years ago I tested the PAXCOUNTER Version from your development tree : 1.7.91 It works without modifying "CLOCK_ERROR_PROCENTAGE 5"
Thank you very much for your support !

Hi cyberman I need support to get PAXCOUNTER jointed via OTAA. HELTEC Lora 32 V2. 10m away from the Lora 8 chanel gateway.
The join works by using a OTAA demo sketch after some seconds. The demo sketch is compiled with ARDUINO 1.8.5 / LMIC 1.5.0+arduino2 library. (https://github.com/matthijskooijman/arduino-lmic)
The join of PAXCOUNTER does not working in my case. In the file of Loraserver the request is recorded and the positive reponse is sent. It looks like that this response is not recognized by the node.
Can you see something in the Logs which may help to find the failure ?
PAXCNT v1.7.841
JOIN REQUEST
JOIN ACCEPT
Do you think there may be a way to get it working ? It would be nice if you find a solution for me.
Best regards from Krefeld, Germany --- Frank
