More than 4 Blynk.virtualWrite ESP8266 re start to connect


I am busy to extent my arduino nano weather station to Blynk. I have 14 values to display for now. Ik extent my nano with ESP8266 12E Dev kit.
and via Serial i receive the data in json string at the ESP al this is tested before started with blynk work oke.

The code as show below works until i enable the 5the Blynk.virtualWrite statement in the code. Then my connection on the ESP constantly restarting and also a stack dump i think.

What do i do wrong?

I’d try putting some; commands in your void sendSensorData() function, maybe after each block of three virtualWrite commands.

I’d also try calling the the sendSensorData function less frequently, at least during your debugging process.


Pete,. Thanks for you reactions. I The mean time i found the solution IT was the amount of memory during when uploading the code i had the lowest balie selecties for the esp8266 do issue solved
