Several requests fail when connecting to web server #95

Hi

I am writing with the hope somebody can give me a hand.

Several request get a 400 'bad request' or 406 'not acceptable' code in return from the web server. Some other times there is not even a response from the server. It seems the connection dies before it reaches the server, since I cannot see any logs on the server console.

Retrying the same request sometimes work.

I have an Arduino Mega 2560 R3 + WiFi Esp8266 with firmware 1.7 (Non OS SDK3).

What could be the issue?

Thanks in advance.

how is it wired? how is the esp8266 powered? what serial baud rate? did you try to turn on debug log?

The esp8266 is embedded. It is part of the Mega 2560 R3 board:

[https://arduinotech.dk/shop/mega-r3wifi-atmega328pesp8266-32mb-memory-usb-ttl-ch340g-compatible-for-arduino-mega-nodemcu-esp8266/]

I know about the serial baud rate for the monitor and the communication between the Mega 2560 and the esp8266 but don't know the baud rate of the esp8266/WiFi. How could I know that?

I haven't tried to turn on the debug log. How do I do that?

Thanks for the help. I am new to Arduino/embedded programming.

This is a typical example where first attempts fails, second works:

how did you upload the AT firmware? I usually see this strange behavior if the wifi calibration data of the esp are corrupted

I used this command:

esptool.py --port /dev/cu.usbserial-144230 write_flash --flash_mode dio --flash_size 1MB 0x0 boot_v1.7.bin 0x01000 at/512+512/user1.1024.new.2.bin 0xfb000 blank.bin 0xfc000 esp_init_data_default_v08.bin 0xfe000 blank.bin 0x7e000 blank.bin

I updated it to the latest version you suggested on a link I found in an Arduino forum.

How could I verify that and calibrate the esp?

During last night the transmission has been quite acceptable just a few retries and every 15 minutes as expected. But sometimes I am unable to see a record in hours.

this is the upload command for a 1 MB flash. the README for WiFiEspAT has the command for larger flash.
erase flash with esptool to reset the calibration data and then upload the AT firmware with the right command.

It seems more stable after the update you suggested. Let's test it for a few hours and let's see how it behaves.

What is the difference?

It seems to fails still but with a little improvement. At least it seems that is not missing data after a few retries.

Let's leave it until tomorrow to get a better sample of data.

There have been a few retries during the night and only one record missing out of 29. Unfortunately I could not see the logs for the missing record. My computer got stuck yesterday in the evening apparently .. :(

Is it possible to improve it with any other adjustments?

Ok I will disable logging also for a while to see how it goes.

I have also removed all delays and all String. I am using F() for the literals.

How can I remove this String? is the only one left:

String request = F("POST ");
request.concat(URI);
request.concat(F(" HTTP/1.1"));
request.concat(F("\r\n"));
request.concat(F("Connection: keep-alive"));
request.concat(F("\r\n"));
request.concat(F("Host: "));
request.concat(String(API_SERVER_IP));
request.concat(F("\r\n"));
request.concat(F("Content-Type: application/json"));
request.concat(F("\r\n"));
request.concat(F("Content-Length: "));
request.concat(tempData.length());
request.concat(F("\r\n"));
request.concat(F("\r\n"));
request.concat(tempData);

logging slows down everything so there can be some loss of data on the Serial to esp8266.
turn off logging or at least log at very high baud rate

Seems more estable now. Sometimes it requires a few retries but it is much better than before. Thank you Juraj.

I will try to replace the String concatenation with char array.

I have managed to move from String to char arrays the last two Strings I was using in the code. Hope that also prevent any memory leaks.

Thanks for the help @JAndrassy. I will check out the difference between both flash commands.

That works thank you @JAndrassy. I am performing last test with a power adapter instead of a power source. Let's hope all is good 🙂

@JAndrassy it is getting better by time. It is the ESP auto calibrating itself somehow?
