Review December 1 of Wemos sensor network.

 REview of where we're up to with "spud sensor" , Boardwalk ESPNow Network Thu Dec  1 11:16:16 NZDT 2022. 



Software used two Arduino programs to talk to two Wemos Mini ESP8266s. One was the sender that sampled temperatures and humidities and sent them through I2C to Wemos I. They were stored in buffers, these samples then sent on to Wemos II via ESPNow. Sometime the sender was in  the garden on the top of the Boardwalk vege place. ESPNow worked well for this job. 

The receiver Wemos waits for orders from serial terminal, including one to send the log file which it gets from the sender, Wemos I. There's a Python program serial13.py that takes 100 bytes of the logged sensor information, tidies it up a bit then can be passed to Excel as a comma delimited file for graphs etc.  So data a goes :

HTU via I2C to Wemos I

Wemos I via ESPNow to Wemos II

Wemos II via serial to Python (or Terminal)

Python file via clicks to Excel

Spud sensor update 3 August 2022

 Sender WemosI going ok. This is driven by C:\Users\Dell\Documents\Arduino\WorkingOctober22\SpudSensor94H\SpudSensor94H.ino which takes values of temperature and humidity from HDU21 device,with  SparkFun driver, and sends these values to Wemos II, the Listener. Listener's display on serial terminal looking a bit crude but works OK. https://pastebin.com/Fvw5NZbS is the Sender program that reads the HUD21 device and sends info. via espNow to Listener program on WemosII below.. C:\Users\Dell\Documents\Arduino\WorkingOctober22\SpudSensor94H\SpudSensor94H.ino https://pastebin.com/TGdvqSh5 is the Listener program C:\Users\Dell\Documents\Arduino\WorkingAugust22\SantosSensor7\SantosSensor7.ino (NB not ...Sensor6.ino above. Slight improvement. Next task is to tidy up listener code and include semaphore codes that help transfer file chunks from Sensor to Listener. Codes currently are 51 = normal file chunk being delivered from Sensor 59=last fule chunk-ette of extras. (<200 bytes) 11 List

WEMOs mini going

 Having difficulty soldering NRF24L01 holes to header, very small gaps. So gave up on that for the time being and will concentrate for a while on ESP Now via three Wemos minis I bought recently from TradeMe. Did not install new Jason file etc by following  https://www.teachmemicro.com/getting-started-wemos-d1-mini/ who had different Jason file, but I's previously installed one while I was waiting for Wemos Mini's. Blink sketch went off according to plan and now I want to try out some ESP now functions. First, look at a few You Tubes and look for some functions I can call from ESP now library with just one mini . void setup() {   // initialize digital pin LED_BUILTIN as an output.   pinMode(LED_BUILTIN, OUTPUT); } // the loop function runs over and over again forever void loop() {   digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)   delay(100);                       // wait for a second   digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by
