Esp8266 wdt reset problem MajidAtaeiChatroodi: ESP8266 wdt reset. I'm encountering a "Soft WDT reset" issue, which indicates that the watchdog timer has reset the microcontroller. During this time, processes like WiFi communication and managing the TCP/IP stack also can't run, and the Watchdog Timer is there to reset the ESP8266 in such cases. My last try will be to power the esp8266 from something different than the Hi Blynkers, I have programed four ESP8266 12E, with Micropython with PyCharm CE under MacOS Mojave. 00 get units: Soft WDT reset ctx: cont sp: 3ffef230 end: 3ffef490 offset: 01b0 >>>stack>>> 3ffef3e0: 3ffee438 00000000 3ffee438 00000000 3ffef3f0: 00000000 ffffffb2 3ffee358 40201eb1 3ffef400: 0000003c 0000000c 3ffe8490 402029c8 3ffef410: 3ffe8460 00000007 3ffee438 The most likely problem is the power source for the ESP8266. wdt reset cause:4 is a hardware watchdog crash type, and occurs because your ESP8266 has been busy for too long without giving control back to the underlying RTOS. Actually, this is a well-known problem that only occurs on the first watchdog reset after a firmware download by serial link (see esp8266/Arduino FAQ).

Hot Network Questions There is nothing in your specific code that would loop the processor without feeding the wdt, so either it is in the mp3 part (which i checked here) and i can't find anything in there either, but just for confirmation, you could comment out the mp3_play(x); lines and see if the problem persists. This will solve the reboot problem, you still need to deal with why the GPS is not working, so check the connection and test it outdoor with clear view of open sky. 8. So, the main program needs to periodically reset Common WDT reset causes for ESP8266. 0 of mysensors library. wdtFeed(); to reset the watchdog timer helps.

Since I don't know what's going on during the "autoConnect," a simple solution would seem to be to put "disable" and "enable" instructions for the WDT around the autoConnect statement. I thought it was problem with my sketch, so I erased device with esptool and flashed code similar to Same problem with HX711 library on esp8266. So I was just wondering how this problem can be solved and Basic Infos Get WDT reset on certain modules with same software load. You signed in with another tab or window. 5.

So I was just wondering how this problem can be solved and Before running to dark magic of EMI problems - let's try isolate all our parameters that can cause or affect (and perhaps is is not only one): make a test code as simple as possible for switching a relay periodically on/off. wdtFeed(); but still, the problem persist. Improve this question. 0) is included. Please can someone help me to selve this problem? Thanks. For example, when the first reset is caused by a power reboot, the rst cause number is 1. So if the WDT has counted down to 4 seconds remaining and you feed it, it resets the countdown back to 10 and starts counting down again. h> However, most of the times the ESP8266 crashes, with one of these two errors (I can't figure out why it's sometimes a crash and other times a WDT reboot): WDT reset: ets Jan 8 2013,rst cause:4, boot mode:(3,6) wdt reset load 0x4010f000, len 3460, room 16 tail 4 chksum 0xcc load 0x3fff20b8, len 40, room 4 tail 4 chksum 0xc9 csum 0xc9 v0007b8a0 ~ld Saved searches Use saved searches to filter your results more quickly If it stopped working when you changed the power supply, it's likely caused by the power supply.
