I tried with the following code given and found that there is no error with the code . I found a problem that when i remove data jumpers from ESP8266 NodeMCU, values will update to cloud (all values are zeros), but when i reconnect the jumper wire which receives data from sensors (i am mapping data from UNO to nodeMCU), it is giving as ‘ wdt reset’.
But when i dont use Cayenne library functions, i get serial data from sensors. this doesnt work when i connect to Cayenne
I want your help
Thank you
