@mathieu Hi!

I have sent the initialization code to your e-mail (I have included your full commands there, but not here on the forum).

Basically, the commands are sent in a non-blocking fashion one-by one:

#include <BLEDevice.h> #include <BLEServer.h> #include <BLEUtils.h> #include <BLE2902.h> #include <pgmspace.h> const char* const commands[] PROGMEM = { "|LB UID:lb0 X:20 Y:10\r\n", ... ... ... }; const size_t numCommands = sizeof(commands) / sizeof(commands[0]); namespace uuid { static const char *SERVICE_UUID = "6E400001-B5A3-F393-E0A9-E50E24DCCA9E"; static const char *RX_CHARACTERISTIC_UUID = "6E400002-B5A3-F393-E0A9-E50E24DCCA9E"; static const char *TX_CHARACTERISTIC_UUID = "6E400003-B5A3-F393-E0A9-E50E24DCCA9E"; } // namespace uuid // forward declare parser for incoming messages void parseGuioMsg(const String &msg); // setup done flag bool setupDone = false; // init active flag bool initActive = false; // send command period in msec static const unsigned long sendCommandPeriod = 50; // custom handling of server callbacks class CustomBLEServerCallbacks: public BLEServerCallbacks { void onConnect(BLEServer* pServer) { Serial.println("Connected!"); }; void onDisconnect(BLEServer* pServer) { Serial.println("Disconnected!"); // fix provided by BM // restart advertising after disconnect, otherwise GUI-O cannot re-connect if(setupDone) { // restart advertising on disconnect delay(500); pServer->startAdvertising(); } } }; // custom handling of characteristic callbacks class CustomBLECharacteristicCallbacks: public BLECharacteristicCallbacks { void onWrite(BLECharacteristic *pCharacteristic) { std::string msg = pCharacteristic->getValue(); // parse message string parseGuioMsg(String(msg.c_str())); } }; // global ptr BLECharacteristic *pTxCharacteristic; void setup() { // debug output Serial.begin(115200); // create device BLEDevice::init("BasicBLE_NUS"); // create server and register callback BLEServer *pServer = BLEDevice::createServer(); pServer->setCallbacks(new CustomBLEServerCallbacks()); // create service BLEService *pService = pServer->createService(uuid::SERVICE_UUID); // crate Tx characteristic and add descriptor pTxCharacteristic = pService->createCharacteristic(uuid::TX_CHARACTERISTIC_UUID, BLECharacteristic::PROPERTY_NOTIFY); pTxCharacteristic->addDescriptor(new BLE2902()); // crate Rx characteristic and register callback BLECharacteristic *pRxCharacteristic = pService->createCharacteristic(uuid::RX_CHARACTERISTIC_UUID, BLECharacteristic::PROPERTY_WRITE | BLECharacteristic::PROPERTY_WRITE_NR); pRxCharacteristic->setCallbacks(new CustomBLECharacteristicCallbacks()); // start the service and start advertising pService->start(); pServer->getAdvertising()->start(); // setup done flag setupDone = true; } void loop() { static size_t currentCommandIndex = 0; static unsigned long lastCommandTime = 0; if (initActive) { if (currentCommandIndex < numCommands) { if (millis() - lastCommandTime > sendCommandPeriod) { lastCommandTime = millis(); // retrieve and send the command char commandBuffer[256]; strcpy_P(commandBuffer, (char*)pgm_read_ptr(&commands[currentCommandIndex])); sendMsg(commandBuffer); Serial.print("Sending: "); Serial.println(commandBuffer); currentCommandIndex++; } } else { initActive = false; // hide loading screen sendMsg("@hls\r\n"); } } } /***************************/ /* IMPLEMENT YOUR GUI HERE */ /***************************/ void sendMsg(const String &msg) { pTxCharacteristic->setValue(std::string(msg.c_str())); pTxCharacteristic->notify(); delay(50); } void parseGuioMsg(const String &msg) { if(msg.startsWith("@init")) { Serial.println("GUI-O app is requesting INITIALIZATION!"); // clear screen and set background sendMsg("@cls\r\n"); sendMsg("@guis BGC:#FFFFFF\r\n"); sendMsg("|SORI UID:sori2 HID:sori ORI:2 SEN:0\r\n"); // wait for orientation change (alternatively catch GUI-O screen orientation change event...) delay(500); // show loading screen sendMsg("@sls\r\n"); initActive = true; } }

Can you please test it and see if it works for you?

You can try extending sendCommandPeriod if you have any issues... Also you can comment out the @sls and @hls commands to see exactly what is going on...

@Fehr No problem!

I plan to write a FAQ page on GUI-O website, which will also include this explanation.

Best regards,
Kl3m3n

@Bernard Hi.

Navigate to "Info" and tap on "Powered by GUI-O version..." 10 times. A new menu will appear at the bottom.

You can see the Developer mode section in the manual for detailed information.

Best regards,
Kl3m3n

@Bernard I am glad that you've solved it!

@gammda has made some great projects in the past, so he is definitely a GUI-O expert! 🙂🙂

Best regards.

@etravnik Hi!

Can you please tell me which connection mode you are using (Bluetooth, IoT...)? Can you provide a minimal example which reproduces the problem?

Best regards,
Kl3m3n

@kl3m3n
The new release (1.0.73) fixed the problem with the wrong? keyboard on my Samsung tablet.
I was then able to connect to GUI-O Live Design, and downloaded the TemperatureReader.gdp. All appears to work, although I am struggling to do anything different with the Designer in these early stage
Good job - thanks.
Cheers
Steve

@SteveV

No problem! Thanks for the feedback 🙂

If you have any more issues, feel free to ask!

Hi @kl3m3n,

I see, thank you

Hello @kl3m3n,

You are right, tested it now with two Esp32 and it works.

Thanks

Hello @kl3m3n,

I've already answered in the other thread

Hello @kl3m3n,

I raised this question to understand how many hobbyists and professionals are in the Gui-O platform community.

In my case, I have been developing a product for commercial purposes for which I am still seeking investors. The market for the product is global.

I am of the opinion that in the case of commercializing products developed and produced using the Gui-O platform, you should also benefit from a percentage of the profit from the solution (product + Gui-O).
I believe this is well-deserved, and there is no reason to think otherwise.

In commercial terms, the most important aspect is not only the value you can derive from the Pro version registration, perhaps with hobbyists, but if you consider the example I provided, that client has approximately 55 employees, which would represent the same number of Pro version registrations. By entering into a partnership as you mentioned,

"This means you get an apk that you can distribute to your users on your own terms,"

you would end up with much more financial return. For example: 7000 x €4 = €28,000
This is an example, and the value depends on the type of final product, but at a minimum, this would be the amount, and reimbursement in most cases would not be immediate but rather phased over time. Clients buy it according to their needs and financial capacity.

By maintaining the commitment in all future projects, you would be optimizing the monetization of your work. The apk issue would provide the necessary security for all of us to make commitments with end customers, making it possible to commercialize the solution of product (pcb) + Gui-O in a win-win manner.

Give it some thought. In my case, I will continue to try to find clients for the solution, but I am already more reassured knowing there is openness to leverage this good solution for both sides.

I hope that other professional users can join this partnership model and share their opinions.

@kl3m3n
yes, I stupidly took the Arduino sketch that I used in February, without checking all the parameters! I hope that my thoughtlessness will be useful to others......
Kind regards and thank you Bernard

Hi @kl3m3n,

Ok, understand
Thank you

@Bernard Hi.

To retrieve only the day of the week, you can use the RTCF parameter as such:

"|RTC UID:rtc0 HID:rtc RTCF:dddd\r\n"

You can also use abbreviation:

RTCF:ddd

or numerical form with leading zero:

RTCF:dd

or without:

RTCF:d

For more information about formatting, see the manual, Appendix C (Supported date and time formats).

Note: The formatting does not support spaces, so you need to use e.g., underscore or hyphen or similar to build your own timestamp.

@enniom Hi!

Currently there is no such feature to store the files outside the application folder. I will take a look into this a bit after I make some necessary adjustments to fully support targeting Android 13.

Hi @kl3m3n,

Thanks, I know this chip, but never used it

I have done in the last 20 years almost all my projects with Bascom and Atmega and Xmega microcontrollers, but there are no libraries like in the Arduino, you have to code everything from scratch. With the Esp32 this task is easier, for this there is the lib can.h and you only need the soic8 driver for the bus.

The advantage is that the Atmega88PA is cheaper than the Esp32 but I will still think about which one to choose

Thanks for the attempt to help

Hi Kl3m3n,

A sincere thank you.
The whole process seems to be quite complex. In my case, it is for Windows.
I am trying to get a fixed IP. The ISP operators want a high value. I will look for cheaper ones.
In the next few days I'll try to install it and do some tests. I will give you my feedback then.
Thanks again for your support.

Best regards

Hi @kl3m3n,

Not see it, thank you
In a few days i will test it and give feedback

Best regards

@enniom Thanks for the feedback!
