I try to connect a few ESP8266 (STA-Mode) to one ESP8266 (AP Mode)

All of the ESP Stations connect well, but one will not connect. The one can connect to other networks.

Debug Serial off well connecting ESPs:

15:03:31.355 -> fpm close 3 
15:03:31.355 -> mode : sta(c8:c9:a3:57:c7:2e)
15:03:31.402 -> add if0
15:03:31.402 -> ..scandone
15:03:33.605 -> scandone
15:03:34.492 -> state: 0 -> 2 (b0)
15:03:34.492 -> state: 2 -> 3 (0)
15:03:34.492 -> state: 3 -> 5 (10)
15:03:34.492 -> add 0
15:03:34.492 -> aid 1
15:03:34.539 -> cnt 
15:03:34.539 -> 
15:03:34.539 -> connected with cardReaderConfig, channel 1
15:03:34.539 -> dhcp client start...
15:03:34.727 -> ip:10.10.10.101,mask:255.255.255.0,gw:10.10.10.1
15:03:34.727 -> WL-CONNECTED[HTTP] begin...

Debug Serial when I try to connect the one, which is failing:

15:28:39.458 -> fpm close 3 
15:28:39.458 -> mode : sta(bc:ff:4d:f9:91:12)

15:29:03.688 -> cnt 
15:29:04.670 -> ..state: 5 -> 0 (0)
15:29:04.670 -> rm 0

When I try to connect to other networks, it works:

15:09:50.008 -> fpm close 3 
15:09:50.008 -> mode : sta(bc:ff:4d:f9:91:12)
15:09:50.008 -> add if0
15:09:50.008 -> ..scandone
15:09:52.252 -> scandone
15:09:53.139 -> state: 0 -> 2 (b0)
15:09:53.139 -> state: 2 -> 3 (0)
15:09:53.139 -> state: 3 -> 5 (10)
15:09:53.139 -> add 0
15:09:53.139 -> aid 5
15:09:53.139 -> cnt 
15:09:53.186 -> 
15:09:53.186 -> connected with WLAN-AF, channel 6
15:09:53.186 -> dhcp client start...
15:09:53.232 -> ip:192.168.178.94,mask:255.255.255.0,gw:192.168.178.1
15:09:53.232 -> WL-CONNECTED[HTTP] begin...

Hope anyone can help, but assuming this is a hardware problem...

EDIT: I can connect via normal ESP8266Wifi (Wifi Client example script) But get the error when trying via WifiMulti or Enterprise (BasicHttpClient example script).

  • Any idea where "no cardReaderConfig found" is coming from? Commented Sep 22, 2022 at 13:37
  • "cardReaderConfig" is the Network SSID, a bit confusing here I see; So sometimes it even can't find the network, but the ESPs are next to each other. Commented Sep 22, 2022 at 13:45
  • Oh right, I now see it in the first block. Do you know the MAC address of the cardReaderConfig AP? I wonder it if might be the same as the failing ESP (bc:ff:4d:f9:91:12). Commented Sep 22, 2022 at 13:49
  • I can connect when not using WifiMulti (see edit in post) Commented Sep 22, 2022 at 13:55
  • The state changes are interesting: "IDLE (0) > SCAN COMPLETED (2) > CONNECTED (3) > CONNECTION LOST (5)". But only in the failing case it goes back to IDLE, the others connect okay (even though the last state is "CONNECTION LOST"). Puzzling. Commented Sep 22, 2022 at 14:06
