- Thu Apr 02, 2015 7:04 am #13258 Yes, system printf puts stuff right into UART FIFO. Serial.print is a little bit more sophisticated, it has it's own circular buffer in addition to the hardware FIFIO. So using both at the same time will likely lead to issues.

Can you try modifying your code like this?

Code: Select all

if(!client.connected()) {
   client = WiFiClient();
   if(!client.connect(host, port)) {
      state = SOIOs_disconnected;
   }
}

Let me know if that changes anything.

- Thu Apr 02, 2015 8:04 am #13269 i found the "DEBUGV" macro an now i get this output:

the "." are at the start of the loop

the node ping is triggerd by.

Code: Select all

void loop(void) {
unsigned long t;
   static unsigned long last_nodePing;
   t = millis();
//....
   if(abs((t - last_nodePing)) >= (NODEJS_PING_TIME*1000)) {
      nodePing();
      last_nodePing = t;
   }
//.....

it looks like one loop currently need more then 1 sec?

Code: Select all

:err

is from this code:

Code: Select all

void ICACHE_FLASH_ATTR WiFiClient::_err(int8_t err)
{
    DEBUGV(":err\r\n");
    esp_schedule();
}

log:

Code: Select all
