ESP32 crashes after http post
Posted: Sun Jun 25, 2023 12:35 pm
Hi there.
I need to send a dataset to a google sheets spreadsheet using esp32.
For that, I used the library: https://github.com/electronicsguy/HTTPSRedirect
The data is being sent and recorded in the spreadsheet, but as soon as esp32 performs the post, it simply hangs on the post command line: client->POST(url, host, payload, true).
What can I do to make esp32 continue to run normally after the Post command?
On the serial monitor, these are the only messages I got:
*wm:AutoConnect
*wm:Connecting to SAVED AP: VIVOFIBRA-0620
*wm:connectTimeout not set, ESP waitForConnectResult...
*wm:AutoConnect: SUCCESS
*wm:STA IP Address: 192.168.15.171
Client connected
Publishing data...
{"command": "insert_row", "sheet_name": "Registros", "values": "0,1,3,3,4,5,6"}
