NFC function

[Sato]

Hi kl3m3n,

Nowadays most smartphones have NFC.
I leave here the new challenge, is there a way for Gui-O to use this feature?

Regards

[kl3m3n]

@sato GUI-O supports NFC, but this feature is currently disabled. I will enable it, but first I just need to think how to expose it to the user. Possibly through hardware components, similarly as RTC (real-time clock).

Hi @kl3m3n,

As most smartphones have the NFC Reader integrated, in my opinion it is to be able to read a Tag's ID and the Gui-O make that information available for the user to use in any way they need. In this case I don't think any hardware other than the Tag will be necessary.

Best regards

@sato Thank you, I will add it to the list (with low priority).

Hi @kl3m3n,

Ok, i know you have priorities. In my opinion it's an excellent feature. It is a way to know if the connection was remote or local on the equipament, this makes a lot of difference during information management.

@sato NFC feature is implemented in v1.0.15. Please check the new developer manual.

Hi @kl3m3n,

Great. THANK YOU.

Soon i will buy a Tag to make tests and give feedback.

Hi @kl3m3n,

Today received the Tags

mqttClient.publish(&In[0], "|NFC UID:nfc1 HID:nfc SEN:1\r\n");
Gui-O respond with @nfc1 -2

Make NFC on, it receive nothing

Tested with my both Samsung Phones

Attached the picture of the Tags

Hi @kl3m3n,

Forgett to add the data of the Tags read with a NFC read App
Hope it can help

Best regards

@sato Did you write any record to the tag? You need to write at least one plain text record to the tag (GUI-O does not support writing tags). There are may apps able to write the NFC data. Did you consult the manual?

Hi kl3m3n,

Yes I read the Manual, but I must be doing maybe something wrong, because it doesn't work.

In the final part of making the graphical environment I put:
mqttClient.publish(&In[0], "|NFC UID:nfc1 HID:nfc SEN:1\r\n");

mqttClient.publish(&In[0], "|TON UID:ton1 HID:ton EDUR:3000\r\n");

Inside the void loop I have a Timer that periodically runs:

mqttClient.publish(&In[0], "@nfc1 SEN:1\r\n"); // wouldn't even need

mqttClient.publish(&In[0], "@ton1 1\r\n");
Serial.println("TON");

Always plays a short sound

I recorded the text "Hello Gui-O" in a Tag, with an App Tool for NFC. I can read that text even with the internal functionality of the phone, but on the serial port nothing appears.

void parseGuioMsg(const String &msg) {
Serial.println(msg); // @init usr:
variable msg is always empty

To make sure if there is something wrong with my code, I tried it with your example lamp code, but the effect is the same

Here I switch Off the NFC function on the Phone, on tap's on the lamp it shows on serial port.
GUI-O app is requesting LIGHT ON!
TON
SEN:1
@nfc1 -2 dev:OF24 R. Paris Nr.32 usr:
@light_on 1 dev:OF24 R. Paris Nr.32 usr:

GUI-O app is requesting LIGHT OFF!
@nfc1 -2 dev:OF24 R. Paris Nr.32 usr:
@light_off 1 dev:OF24 R. Paris Nr.32 usr:

Perhaps you can see what i make wrong
Thank You

Best regards

@sato Hello!

Regarding the TON component - this component plays the tones builtin the Android device. Their length is predetermined. If you check out the manual, it says:

For TONT -> Tone type number. For reference see:
https://developer.android.com/reference/android/media/ToneGenerator

and

For EDUR -> Duration of tone in msec. Ignored if
tone duration is shorter.
Maximum duration limited to 5000
msec.

Regarding the NFC - if "-2" is returned, it means that NFC is available, but not enabled (see the manual).

You don't need to repeat the messages to enable NFC scanning. Try sending just one message:

Enable NFC detection:
|NFC UID:nfc1 HID:nfc SEN:1

Disable NFC detection:
@nfc1 SEN:0

Do you use Android 12? Do you have latest app version installed (v1.0.16)? There was a minor fix for Android 12 in this version release.

Best regards.

Hi kl3m3n,

Thanks.
With the short sound it's no problem, but the NFC still doesn't work here.
As I informed, the only reaction from Gui-O is @nfc1 -2, I just switch off the NFC on the Phone to see if Gui-O would react.

I don't think I'm doing anything wrong, but if you want I'll send your code example to see if it works.

Yes, i update to the new version

Best regards

@sato There was a mistake on my side. There were some changes in Android 12 that were not handled correctly by GUI-O app. Now it should work - I have tested it on Android 12 and Android 11.

The version that has the fix is v1.0.17.

I would appreciate the feedback.

Thank you.

Well done, congrats!

So, now will see to implement it in my programm

THANK YOU
