Using as Bridge with 3rd party HaLow AP, Scan results in ERROR

[jrigling]

I intend to use the T-Halow as a network Bridge (HaLow to Ethernet) for connecting non-HaLow devices to a HaLow network. This is like Mode 2 in the documentation, except the AP is NOT a T-HaLow device. The AP uses a Newracom chipset. The AP has been tested with another independent device, using a MorseMicro chipset.

This strategy will not use the AT+PAIR= behavior since it will be using an SSID.

The ESP32 is not used in this configuration.

The AP is configured with
BSS_BW=4MHz
Frequency=910MHz
SSID=Wi-Fi
WIFI_PSK=none

The logs below are from firmware huge-ic-ah_v1.6.4.3-29063_2024.8.16_.bin

After setting the BSS_BW and SSID with AT commands, the logs start to include attempts to associate, but the address is FF:FF:FF:FF:FF:FF, which doesn't match the AP. Is this expected?

I also changed the channel list with AT+CHAN_LIST=9100 and the PSK with AT+KEYMGMT=NONE to match the 3rd party AP configuration.

I try to request AT+SCAN_AP so I can then AT+BSSLIST? and see if the AP is discovered. The AT+SCAN_AP returns ERROR

What should I do to understand why the AP SCAN results in an error? Is this causing the STA to not find the AP?

the scan command seem to be broken on the AT firmware. I have also noticed that trying to associate to a newracom device fails, while newracom -> morse works. The halow stack seems to be a little different here. I think you might have to reach out directly to taixin.

Yes ... adding to this ... I have tried to test extensively getting these Lilygo/Taixin devices working with certified 802.11ah Newracom and Morse Micro devices and they do NOT work.

I have reached out to Taixin numerous times asking for assistance, and have got no reply.

From what I can tell, their chipset or firmware are NOT 802.11ah compliant. :-(

This one module is listed on the WiFI Alliance website as being certified ... but maybe not the one on this product?
