I'll have exactly the same problem :(

Hello

I have a exactly same problem with 2v05 version.

NRF.connect("9c:aa:1b:c0:48:3b private").then(function(server) {

or

NRF.connect("9c:aa:1b:c0:48:3b public").then(function(server) {

doesn't work at all. What's wrong?

Yes. Nothing is not connected. I also tried to get flash dump from a new one and reflash. But still no help. Seems more like a hardware poblem now ...

Hello
I've problem with my ESP32. I tried to use KeyPad module and I tried to use Pins like D0,6,8 but suddenly my ESP will not cooperate any more. I've tried to erase flash and reflash with different firmwares and with different baud rates but still no luck.

I'm using WebIDE, there is possible to use "console" also :) But, still no luck. I recompiled without Graphics and still same behavior. Using this following test code:

function onInit(){
  console.log(JSON.stringify(process.env));
  console.log('A: ', process.memory());
  require("ESP8266").logDebug(true);
  require("ESP8266").setLog(2);
  console.log(require("ESP8266").getState());
  console.log('B: ', process.memory());
  var fs = require("fs");
  console.log('C: ', process.memory());
  SPI1.setup({ sck:NodeMCU.D5, miso:NodeMCU.D6, mosi:NodeMCU.D7 });
  E.connectSDCard(SPI1, NodeMCU.D8 /*CS*/);
  console.log('D: ', process.memory());
  console.log(fs.readdirSync());
  console.log('E: ', process.memory());
  console.log(fs.readFileSync("test.txt"));
  console.log('F: ', process.memory());
}

And here is a result:

And xtensa doc says that error "Fatal exception 3(LoadStoreErrorCause)" is described as "Processor internal physical address or data error during load or store [Exception Option]".

http://0x04.net/~mwk/doc/xtensa.pdf

Well well well... now this is strange. I'm able to list content of SD card, but still unable to read or write.

I formatted SD card to FAT32 and wrote a empty file test.txt and then executed same example. Also I tried to use SoftwareSPI, different pins ... but still same behavior .

What I'm doing wrong :(

I've already tried it, many different ways. Still crashing each time. Perhaps someone can try my binaries :) ?

I was using Espruino IDE as expected :) And it does matter if I execute code into flash or ram, crashes both ways. I suspect something else in deeper, but I 'm not able to debug it :(

Thats all my code, what else you need. I can upload here to my binaries. https://www.upload.ee/download/10990396/d43c5ce2825416a80736/espruino_2v04_esp8266_4mb.tgz
Accordingly PINs are right as hardware SPI.

Do you think that software SPI does not work as expected?

Hello

I've compiled my own v204 version of Espruino, using following params:

export FAMILY=ESP8266
export BOARD=ESP8266_4MB
export FLASH_4MB=1
export ESP8266_SDK_ROOT=/mnt/disk1/home/marko/Workplace/Espruino/esp-open-sdk/sdk
export PATH=$PATH:/mnt/disk1/home/marko/Workplace/Espruino/esp-open-sdk/xtensa-lx106-elf/bin
export COMPORT=/dev/ttyUSB0
export USE_FILESYSTEM=1
export USE_NET=1
export USE_TELNET=1
export USE_CRYPTO=1
export USE_GRAPHICS=1
export USE_ESP8266=1
export RELEASE=1

make clean && make $*

And code in Espruino:

    SPI1.setup({ sck:NodeMCU.D5, miso:NodeMCU.D6, mosi:NodeMCU.D7 });
    E.connectSDCard(SPI1, NodeMCU.D8 /*CS*/);
     var f = E.openFile("log.txt", "w");

And constantly it crashes after "reading" or "writing" a file.

Any ideas why it crashes?

UP! Anyone?
Many thanks!

Seems like v197 will work with PN532. But not in v198. Only change what I found is here:
https://github.com/espruino/Espruino/commit/3739ee577d3bc11064b63db61942ac9910da0e3a

@Gordon can you figure out why PN532 does not work in newer versions?

Hello guys
I've set my module to use I2C and using following example:

I2C1.setup({scl:22, sda:21,});
var nfc = require("PN532").connect(I2C1);
print(nfc.getVersion());
nfc.SAMConfig(); // start listening
setInterval(function() {
 nfc.findCards(function(card) {
  print("Found card "+card);
  card = JSON.stringify(card);
  var leds = [LED1,LED2,LED3];
  if (card=="[147,239,211,128]") digitalWrite(leds,1);
  if (card=="[249,192,235,164]") digitalWrite(leds,2);
  if (card=="[4,99,129,114,72,52,128]") digitalWrite(leds,4);
 });
}, 1000);

And I got I2C errors:

Any ideas why basic example does not work? Using ESP32 module.

Why simple button check will fail ??

pinMode(16, 'input_pulldown');
pinMode(17, 'input_pulldown');

setWatch(function(e) {
  console.log("Button 17 pressed");
}, 17, { repeat: true, edge: 'falling', debounce: 50 });

setWatch(function(e) {
  console.log("Button 16 pressed");
}, 16, { repeat: true, edge: 'falling', debounce: 50 });

And result is:

What could cause this :( ?
Other ways is to use setInterval to check digitalRead pin state... but this is not the right way :(

Hello
Is it possible to attach both corest to Espruino software? ESP32 has 2 cores. Core 0 with Task1 and Core 1 with Task2.
Perhaps is possible to attach another Core via C++

E.compiledC("xTaskCreatePinnedToCore(
                    Task2code,   /* Task function. */
                    "Task2",     /* name of task. */
                    10000,       /* Stack size of task */
                    NULL,        /* parameter of the task */
                    1,           /* priority of the task */
                    &Task2,      /* Task handle to keep track of created task */
                    1);");

Thanks!
