After update from revoxhere/duino-coin to v2.6 stand alone nanos work no problems. Here is running AVR I2C v2.5.2 and it is a lot of troubles with nodes.

Please do update and add if you can add serial monitor over network.

Hello, Let me say first that it's a really great project because it permits to use a master and several slaves without a PC and therefore it's possible to use low powering devices. However, I'm wondering if could be possible to make the behaviour of the server, (ESP8260/ESP32) to act as a PC client AVR miner. I say this because the miner (for the server) appears like it is, (an ESP8266 I2C v2.4.7) but working on a low level difficulty due that the job is being done by an arduino. I'm not 100% sure about this, because I'm just starting with Duco but, do you thin that the server could penalyze the miners working this way?

Not related but, only to let you know that arduino pro mini, that runs on 3.3 volts, works great as slave with a Wemos D1 mini as a master, and this can avoid voltage issues when using 5 volts board.

Great Job!

Hi, are you planning to upgrade DuinoCoinI2C ?

upgrading to this release is required. Servers will stop accepting version 2.X miners in a few weeks.

my rig just stop mining last night, tried re uploading code n slave and master but still cannot mine.

ATMega328 with the optimized duino-coin library do about 215-220 H/s, however the server interpret the device as the arduino mega.

The server interpret 190 H/s arround as a standard arduino with dificulty of @6 But with this code 220H/s server rise to dificulty of @16, affecting the reward (which it pays less) and the performance, less submits.

In the few days the performance of the reward has been drop in about 30-40% when usually i do 80-90 DUCO per day, now i do about 40-50 DUCO per day with the same setup.

I have some Atmega8 chips. but i got this error when compiling.

I delete old version, download new. Load sketch in ArduinoIDE, then start compiling. Did i do something wrong ? Show me that output : `Arduino: 1.8.15 (Windows 10), Board: "FireBeetle-ESP32, 80MHz, 115200"

Morning,

I have a small 'rig' set up with 4 Arduino Nanos and an ESP8266 which has been running well, I have installed the latest Client and Server yesterday to try to solve my issue but have had no luck.

The ESP8266 connects correctly to the Wi Fi The ESP8266 correctly identifies the 4 Nano 'slaves' [ ] FreeRam: 41448 I2C Connected [ 0 1 2 3 ] Then cannot connect with:

Connected to WiFi!

Any ideas?

Any possibility to implement the joggling ports like the new feature of the official miners? and maybe an option to ping the server ip+ports if it will response, otherwise will choose on list of specified ports.

Hi, I have a problem . hosting 10 arduino uno r3 with Esp8266 but when it connects, it disconnects after a few minutes and no longer connects. What's the problem?

I got an ESP8266-01 as master and 2 arduino uno, 1 arduino nano, 1 arduino pro mini atmega328 as slaves and everything is perfect. I love it.

The issue comes up with 2 arduinos pro mini with atmega168 the normal code is too big for those arduinos, the lack of memory make them impossible to work fine. Someone knows how to get the code more smaller please, I would love to put them to work together.

Thanks in advance.

Im getting nearly the same profit for 1 Arduino over I2C as 11 Arduinos over I2C? Is that correct?

With 1 ATtiny1614 running 16Mhz im getting 250H/s hashrate and a calculated profit of 3-4 Ducos/day. With 11 ATiny1614 running 16Mhz im getting total 2 730 H/s hashrate but only a calculated profit of 7 Ducos/day?

Shouln´t it be more like 20-30 Ducos/day, or at least 12 Ducos/day? (4 miners with 100% efficiency)

Regards

To Reproduce Steps to reproduce the behavior:

1. Connect 1 miner, check calculated earnings.
2. Connect 11 miners, check calculated earnings.
3. Calculated earnings not multilied according to the kolka system

Expected behavior 20-30 Ducos/day, not 7 Ducos/day

Arduino (please complete the following information):

• Arduino IDE 1.8.13
• DuinoCoinI2C 3.0 release

Additional context Add any other context about the problem here.

Describe the bug Hi, im Reza. I want to ask, regarding mining duco coin I2C, I used 1x esp 8266 and 4x arduino uno R3, at first everything went well ESP8266 connected to the internet And the wallet status was detected by AVR Minner, but after a few hours, suddenly AVR Minner not detected? What's the solution? Thank you.

is it possible to setup master and slave on ESP-01? I am not sure why I keep getting Job Bad incorrect difficulty. usually, ESP-01 can reach 1500 diff, but in my case only 6 diff. thank you..
