We have a live TCP socket from each of the device to local server. This socket reattempts connection if device doesnt hear from server for 20sec. Everything runs smoothly for a period of time and then suddenly devices start disconnecting and reconnecting to this TCP socket. This goes on for around 1hr or so and then most of the time situation self resolves. If we restart the access point/router we see improvement in the situation but it does recur. During the period of 'reconnections' even HTTP requests from devices to server start to fail. Pings from server to device IP times out too. We can see in access point that the device is stil...

    ESP32 Arduino Sketch and Google Sheets Script We are looking for a skilled developer to create a simple ESP32 Arduino sketch along with a script for Google Sheets. The purpose of the following system will be to determine when an ESP32 starts running and when it stops running and to determine how long it was running for and how long it was not running for. Create an Arduino sketch running on an ESP32. The sketch will send a message to a Google Sheet every ten seconds. Create a Google Sheet to receive the messages and record the time when messages are received. The first message after a period of not receiving any messages will be a start time. When new messages are received, the time elapsed between the start time and the current message will be calculated an...
