Hi I got this error when I try to power esp.

Exception (29):

there is a problem during the WiFi init.
I see too possible reasons atm:

  • instabile power (what power supply do you use?)
  • WiFi config in flash corrupted

flash a sketch with: 

void setup() {
    WiFi.softAPdisconnect(true);
    WiFi.disconnect(true);
}
void loop() {}

and then try yours again.
if this still not helps:

void setup() {
    ESP.eraseConfig();
    ESP.reset();
}
void loop() {}

use the Esp Exception Decoder to see where the problem is coming from.
https://github.com/esp8266/Arduino/blob/master/doc/Troubleshooting/stack_dump.md

at the first look its a null ptr usage or flash access problem.
the stack dump will show more.

I use a 12V 1000mA source then I use a step-down to 3.4V (LM2596S)

Gonna try those sketches.

alinleonard picture alinleonard on 18 Feb 2016

Also please check that your flash size setting in the IDE matches the size of the flash chip. There is a CheckFlashConfig example, please run it on your board.

I have the same problem. I got a sketch to run that only uses WiFi.mode(WIFI_AP) but not in station mode. Also I had a test sketch crash that did not even use any wifi configuration.
I tried ESP.eraseConfig() as well ass disconnecting AP and wifi as suggested by @Links2008. The flash maybe corrupted/broken perhaps?

The sketch works fine on other modules, just not this particular one.

Never Surrender ;^)
Past 3 days investigating an error:
On COM Monitor with WiFiScan, after Build/Upload I was always getting an “Exception (29)” error.

On this page the second suggested solution (‘if this still not helps’) worked wonders:

i'm getting THE SAME

and it's not Flash size, or wificonfig if i flash my previous firmware runs ok
but now i'm trying to open TCP and UDP ports, and running with
Global variables use 64,012 bytes (78%) of dynamic memory, leaving 17,908 bytes for local variables. Maximum is 81,920 bytes.

after connect, i get the same error

I'm getting the same error.
It turned out that I had a variable allocating too much space. Reducing this variable by 10k resolved the problem.

Can somebody please guide me

sou novo aqui (brazil).
se não estiver executando o som das notificações podem usar este json:
String data = "{";
data = data + "\"to\": \"token_aplication\",";
data = data + "\"notification\": {";
data = data + "\"body\": \"temperatura alta!!!\",";
data = data + "\"title\" : \"Alarm\" ";
data = data + "\"sound\": \"default\","; // executa o som do sistema padrão de notificações..
data = data + "\"priority\" : \"high\" ";

data = data + "} }";

Também se tiverem problemas com Exception (29) podem executar o código da seguinte forma:
a parte de envio do do request http fica dentro de uma função:

void send_dados() {
WiFiClientSecure client;
String data = "{";
data = data + "\"to\": \"token_aplication\",";
data = data + "\"notification\": {";
data = data + "\"body\": \"temperatura alta!!!\",";
data = data + "\"title\" : \"Alarm\" ";
data = data + "\"sound\": \"default\",";
data = data + "\"priority\" : \"high\" ";
data = data + "} }";

Serial.println("Send data...");

if (client.connect(fcmServer, 443)) {
Serial.println("Connected to the server..");
client.println("POST /fcm/send HTTP/1.1");
client.println("Host: fcm.googleapis.com");
client.println("Authorization: key=");
client.println("Content-Type: application/json");
client.print("Content-Length: ");
client.println(data.length());
client.println();
client.println(data);
}

Serial.println("Data sent...Reading response..");
while (client.available()) {
char c = client.read();
Serial.print(c);
}
Serial.println("Finished!");
client.flush();
client.stop();
}

Colocar este código dentro de uma função que instância WiFiClientSecure client e depois detroir esta instância, possibilitou exito no meu projeto. pois o código original do post causava Exception (29) depois de uma requisição de envio de mensagem, ou seja, a primeira mensagem era enviada mas da segunda em diante não.

I was getting the same issue then i tried the 2nd suggestion
void setup() {
ESP.eraseConfig();
ESP.reset();
}
void loop() {}
and now ESP is not working properly. Getting unreadable data in Serial Monitor. Can anyone help me with this issue?

@sadiqueimam you've probably already done this, but check you've got your serial monitor listening to the right baud rate

Simply erase template field and save worked for me.
