Okay great. What more can I do to diagnose why the Conduit running MP Packet Forwarder is often not transmitting the join-accept over the air?
I note in the logs above that 2019-03-31 10:35:33 10:35:32 WARNING: a downlink was already scheduled, overwriting it... often appears. Could the downlink be being scheduled rather than transmitted?
I tried adding "logger": true to the .conf file but it didn’t seem to make any difference.
If we can crack this it seems we’d be on the verge of cracking many more mysteries, like:

Hello,
I am using mdot as node. I can see in the TTN console:
*The join requests sent by the mdot
*The join ACCEPT sent by the gateway
But my node can’t receive it.
I used this code to test OTAA on my mdot:
#include "mbed.h"
#include "mDot.h"
#include "MTSLog.h"
#include "MTSText.h"
#include <string>
#include <vector>
using namespace mts;
#define MIN(a,b) (((a)<(b))?(a):(b))
#define MAX(a,b) (((a)>(b))?(a):(b))
// AppEUI
uint8_t AppEUI[8]={...};
// AppKey
uint8_t AppKey[16]={....};
// …
Just to add something useful to this topic. Found some spare time this evening and decided to try an OTAA join with different hardware. I used an original Arduino Uno (5v with 16Mhz crystal) and a RFM95W chip. Connected the inputs/outputs of the RFM95W directly to the Uno using some soldering of jumper wires. The most “dirty” way of prototyping the Mobilefish.com website .
Added a sensor to TTN, used the example that came with the LMIC library and powered it…
Happy to contribute my new Multi-tech Conduit to TTN for Breda, NL region, however I am having some issues receiving JoinAccept messages for OTAA on my mDot. I am using https://developer.mbed.org/teams/MultiTech/code/mDot_LoRa_Connect_Example_APP_EUI_KEY/ as an app starting point.
JoinRequest message is received by Conduit and forwarded to TTN router. UDP trail:
Gateway -> TTN (tcpdump udp port 1700)
