Hmm, seems to be a huge thing, still get this when writing

Edit: GIT_COMMIT: "3076d5133" ups this is not the latest commit

see this conversation Howto write modules to storage?

Is this what you see too? I'll have a look and see if I can figure out what's broken

Yes, I see that too.

Yes, perfect. Many thanks for implementing all this super helpfull stuff.

Wow, way to easy - many thanks for clarification!

Is this possible via command line too?

No spiff, because it is not necessary, the method you can use is described in #5

read Hello
write world
read world

so write changes the value from Hello to world in my test, but the leds on D19 did not switch on and off.

but the event is not fired, or is something wrong with my test code?

digitalWrite(D19,0);

function blink(duration){
  digitalWrite(D19,0);setTimeout(()=>{digi­talWrite(D19,0);},duration);
}

NRF.setServices({
  0x1901: {
    0x1902: {
      value : "Hello",
      broadcast : true,
      readable : true,
      writable : true,
      notify : true,
      indicate: true,
      onWrite: (event) => {
        console.log("Got: ", event);
        blink(5000);
      }
    }
  }
});
// edit
Serial1.setConsole(1);

Using now GATTBrowser to check the service and the custom characteristics, look fine to me.

Check issue #1777 Improve ESP32 implementation for fixed and open issues. Gordon implelemnted the uart part and it works perfect.

This is the way I try to use:

• load file into WebIDE ( see attached screenshots, ide complains )
  
• change upload destination to storage
  
• enter the new filename
  
• upload
  
  

Did the upload and got errors, guess I am missing something.

I will run some test before creating a pr.

@fanoush nice finding, will create a pr for this, so it will be part in one of the next ES32 builds.

ok, there are 3 line of code in MQTT.js that cause this.

line 234

this.client.write(fromCharCode(TYPE.PING­RESP << 4) + "\x00");
// change to 
this.client.write(fromCharCode(TYPE.PING­RESP << 4,0));

line 320

this.client.write(fromCharCode(TYPE.DISC­ONNECT << 4) + "\x00");
// change to
this.client.write(fromCharCode(TYPE.DISC­ONNECT << 4, 0));

line 386

this.client.write(fromCharCode(TYPE.PING­REQ << 4) + "\x00");
// change to 
this.client.write(fromCharCode(TYPE.PING­REQ << 4,0));

Just created a pr for this and added a screenshot using it as MQTTX-S without errors.

Hmm, ist does not work with MQTT.min.js

>mqtt = require("MQTT-S")
Uncaught SyntaxError: Got EOF expected '}'
 at line 1 col 3902
....write(f(e.DISCONNECT<<4)+"")}catch(a­){return this._scktClo...
                              ^

use curl -O https://www.espruino.com/modules/MQTT.mi­n.jsto download that module and use this code to upload to storage.

s = require("Storage");

module=`
<content of file MQTT.min.js>
`;

s.write("MQTT-S",module.replace(/[\n\r]/­g, ''));

Now you can use it like this:

s = require("Storage");
mqtt = require("MQTT-S");

As this does not happen to often, I am fine with those manual steps ;-)

Many thanks for your quick response. Yes the WebIDE will always reload the module. Small modules I manually store and add S to the stored name like in this case it will be MQTT-S. Missed that feature of the WebIDE to upload modules to strorage, will definitl give it a try.

Copy paste from browser to the WebIDE does not look nice.

Sometimes uploading is taking too long because you use larges modules like MQTT. Is there an easy way to save the loaded module to storage. So next time you uses mqtt = require("MQTTS").

s = require('Storage');
mqtt = require("MQTT");
print(Modules.getCached())
/* output
[ 
  "MQTT", 
  "Storage"
 ]
*/

// save cached module 
s.write("MQTTS", /* howto ?*/);
 

Wow, many thanks!

Thanks, so will dig here Non-Volatile Storage for a solution.

// esp32/build/app/partitions_espruino.csv
....
nvs,data,nvs,0x9000,12K
....

Found this tool named Espressif-NVS-Analyzer to decode the nvs data.

Hi, there is that espouse.py on GitHub that can read the efuse data.

// disable BT
ESP32.enableBLE(false);
//this can onyl be reverted by another call with true as argument

now reading the efuse section

espefuse.py summary --format json --port $COMPORT | grep _BT -A6
    "DISABLE_BT": {
        "bit_len": 1,
        "block": 0,
        "category": "config",
        "description": "Disables Bluetooth",
        "efuse_type": "bool",
        "name": "DISABLE_BT",
        "pos": 1,
        "readable": true,
        "value": false,
        "word": 3,
        "writeable": true
    },

"value" : false does not match the expected result ....

Any hints?

check this page for idf-release-and-soc-compatibility and this one for -C3 details

That would be great!

Many thanks fanoush, very interesting feature!

I missed the espruino command line tool that can upload files to storage via myfile.js containing a save to storage command with the wanted content. So all fine.
