strange WIFI ok with EXTERNAL 3v3 but NOT on 220v #4263

hello; i have one BASIC SONOFF flashed with TASMOTA 6.30. nearly works with an external supply: serial log: 00:00:00 Project sonoff Sonoff (Topic sonoff, Fallback DVES_092580, GroupTopic sonoffs) Version 6.3.0-2_3_0 00:00:00 WIF: Connecting to AP2 Tenda_1 in mode 11N as sonoff-1408... 00:00:09 WIF: Connect failed with AP timeout 00:00:10 WIF: Connecting to AP1 SFR_29E8 in mode 11N as sonoff-1408... 00:00:16 WIF: Connected 00:00:16 DNS: Initialized 00:00:16 HTP: Web server active on sonoff-1408.local with IP address 192.168.1.155 00:00:16 RSL: INFO1 = {"Module":"Sonoff Basic","Version":"6.3.0","FallbackTopic":"DVES_092580","GroupTopic":"sonoffs"} 00:00:16 RSL: INFO2 = {"WebServerMode":"Admin","Hostname":"sonoff-1408","IPAddress":"192.168.1.155"} 00:00:16 RSL: INFO3 = {"RestartReason":"Power on"} 00:00:16 RSL: RESULT = {"POWER":"ON"} 00:00:16 RSL: POWER = ON 17:51:13 RSL: STATE = {"Time":"2018-11-03T17:51:13","Uptime":"0T00:00:25","Vcc":2.969,"POWER":"ON","Wifi":{"AP":1,"SSId":"SFR_29E8","BSSId":"44:CE:7D:33:29:EC","Channel":6 ,"RSSI":84}}

BUT when running with SONOFF directly on 220v, i get: 00:00:16 CMD: 00:00:16 RSL: RESULT = {"Command":"Unknown"} 00:00:23 WIF: Connect failed as AP cannot be reached 00:00:23 WIF: Connecting to AP1 SFR_29E8 in mode 11N as sonoff-1408... 00:00:31 WIF: Connect failed as AP cannot be reached 00:00:31 WIF: Connecting to AP1 SFR_29E8 in mode 11N as sonoff-1408... 00:00:41 WIF: Connect failed with AP timeout 00:00:42 WIF: Connect failed as AP cannot be reached 00:00:42 WIF: Connecting to AP1 SFR_29E8 in mode 11N as sonoff-1408... 00:00:50 WIF: Connect failed with AP incorrect password 00:00:51 WIF: Connect failed with AP incorrect password 00:00:52 WIF: Connect failed with AP incorrect password............

Restarting on external 3v3 the wifi is well recognized and the password is good again !

so not usable unless some give me answer... thanks in advance regards apas

Some sonoff basic's have limited power and fail on wifi during the initial boot process.

We have attempted to address this issue with a binary release specific for sonoff basic modules.

Please try the binary from http://thehackbox.org/tasmota/sonoff-basic.bin and provide feedback if it solves the problem for you.

If the tipp from andrethomas didnt solve your issue, the basic is probably for the bin....

wasi54 commented 5 years ago

Check esp8266 issue #105 and compile with additional Flag: build_flags = -D NO_EXTRA_4K_HEAP This solved similar Issue with my Sonoff Basic

Jason2866 commented 5 years ago

@wasi54
This is as standard defined in sonoff.h #define NO_EXTRA_4K_HEAP // Allocate 4k heap for WPS in ESP8166/Arduino core v2.4.2 (was always allocated in previous versions)

So you have used snake oil....

apas2 commented 5 years ago

Hello to all thanks for helping I solve the problem in a curious way: the initial build was made with a fixed IP in config.h 192.168.1.150 or 151, 152... (I precise: each module was rested separately and there is none address conflict). With it I have descripted trouble (ok on external 3v3 and no connection on main 220v)... BUT i recompiled changing fixed IP with 0.0.0.0 that lets DHCP BOX determining SONOFF IP (it was the only change i have done) THEN IT WORKS either on external 3v3 or with 220v main... I had to set static IP by the MAC in the BOX, but it works fine

By the way, voltage status was better in 220v than in external 3v3 (I did note exact values, but I have checked this in the begining)

Again thank for your help It is working now even I dont know why ;-) I dont know if it can be marked as SOLVED

Same problem here after upgrade to 6.3.0 from 5.1.4 - no connection with AC powered only when connected to PC. I am using the ready compiled binaries - not compiling myself. found an simular issue with a missing capacitor - but that did not helped. Downgraded to 5.1.4 and the device connects to Wifi in seconds with AC powered.

I just tried your special version (http://thehackbox.org/tasmota/sonoff-basic.bin): This is working for me. It takes much longer than 5.1.4 to connect to Wifi - about 12 sec compared to 1 or 2 sec before, but it can connect :-) 00:00:00 Project sonoff Gaszähler (Topic sonoff, Fallback Gas_18BAF8, GroupTopic sonoffs) Version 6.3.0.2-2_30 00:00:00 WIF: Connecting to AP1 FRITZ!Box Fon WLAN 7390 in mode 11N as sonoff-6904... 00:00:12 WIF: Connected

I am having a similar issue but only with my two KNX devices. On 3.3v they aare fine but on 110V AC they connect and seem to stay connected but accessing them through the web interface is hard. It will load sometimes but more often than not it won't. Sending commands to them is hit or miss too. I did try 6.3.0.2 with the same results. Went back to 6.2.1 and all is fine. My other non KNX basics are fine on 6.3.0.

andrethomas commented 5 years ago

@Sym-Link This is indicative of the power supply restraints we have found on some sonoff basics - Unfortunately KNX is not enabled for the sonoff-basic.bin so the best resolve here would be to build a custom binary for yourself whilst disabling all the drivers you do not need and setting AP_SLEEP 5 in user_config to reduce cpu demand and indirectly power demand.

Closing this issue as @apas2 said that now it is solved.
