Ok so now I have a new issue, when configuring both nodes as follows:
```bash
ifconfig 7 set phy_mode ofdm
2019-09-30 13:56:53,946 - INFO # ifconfig 7 set phy_mode ofdm
2019-09-30 13:56:53,962 - INFO # success: set PHY mode of interface 7 to OFDM
> ifconfig 7 set option 4
2019-09-30 13:57:06,191 - INFO #  ifconfig 7 set option 4
2019-09-30 13:57:06,192 - INFO # success: set OFDM option on interface 7 to 4
> ifconfig 7 set scheme 2
2019-09-30 13:57:14,131 - INFO #  ifconfig 7 set scheme 2
2019-09-30 13:57:14,147 - INFO # success: set modulation/coding scheme on interface 7 to 2
```

Pinging fails again:
```bash> ping6 fe80::2068:3123:94f1:9637%
2019-09-30 13:58:00,951 - INFO #  ping6 fe80::2068:3123:94f1:9637%
2019-09-30 13:58:03,960 - INFO #

2019-09-30 13:58:03,965 - INFO # 3 packets transmitted, 0 packets received, 100% packet loss
```

However, I tried changing to FSK earlier and that did work flawlessly though.

Just for completeness sake, here are the ifconfig printouts of both nodes:
