I support, as an embedded systems developer who can’t code mobile apps at this time. IoT is a BIG thing ---

Just to update this thread with something that I haven’t found announced: BLE now works on iOS even in Thunkable Live app! Somehow it just started, even if it still has a warning in Live Test. So, @domhnallohanlon, you can remove the warning - it works now 🙂 ---

Even more good news - BLE component was silently updated - no announcement on that too! I have just noticed new options, but you have to click on the block itself, they are still not available in the blocks pane: ![Screenshot 2020-09-09 at 11.54.47](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/a/9/a9c118488205bd70cbda48eaeb376d9b84ddb78c.png) By now, I have tested only the Disconnect function, AND IT WORKS!!! 😃 😃 🙂 I’ll test the others and report, but this is really good news for us working with BLE! Thanks @domhnallohanlon and please announce these updates! ---

A couple of you have asked me about the ESP32 talking (RX/TX) to Thunkable X. Below is the crux of my Arduino handshake code. It uses nkolban BLE libraries… I am concatenating packets of 20b directly into a SPIFF file. … class MyCallbacks: public BLECharacteristicCallbacks { char lastpacket[41] = {’\0’}; char check[41] = {’\0’}; File packets = SPIFFS.open("/uploadstring.txt", FILE\_APPEND); std::string pw = SPIFF\_string\_delim\_eol("/credentials.txt", “|pw|”);//custom function called ``` void onWrite(BLECharacteristic *pCharacteristic) { std::string rxValue = pCharacteristic->getValue(); if (rxValue.length() > 0) { packets.print(rxValue.c_str());//append packet to file. strcat(lastpacket, rxValue.c_str());// ***constantly tagging two consecutive packets to check unbroken password or other keywords.*** strcpy(check, lastpacket); strcpy(lastpacket, rxValue.c_str()); pTxCharacteristic->setValue(rxValue);// ***send Thunkable back the packet for checksum.*** if (strstr(check, pw.c_str()) != NULL && check[strlen(check) - 2] == '~' ) { // ***check for flag sent by Thunkable. security password variable confirms credentials, integrity and end of packet.*** packets.close(); Serial.println("success");//Serial monitor pTxCharacteristic->setValue("success"); // ***this is sent to Thunkable on completion*** // btStop(); // ***Now using Thunkable to disconnect*** } } } ``` }; … I will eventually get around to documenting my project which I will be happy to share excerpts of including Arduino / Firebase / Thunkable three way communication. Sorry for the brevity guys but I never was much good at documentation and explanation of my modules. We all have our weaknesses 🙂 ---

This is exactly what I have been searching for and others too… Adding the bellow \*\* \*\* portion to the existing code worked perfectly. So many people were blaming thunkable (The, requiring the BLE receive to be an EVENT block aside) pCharacteristic = pService-\>createCharacteristic( CHARACTERISTIC\_UUID\_TX, BLECharacteristic::PROPERTY\_NOTIFY\*\*|BLECharacteristic::PROPERTY\_READ\*\* ); Top man Mark @ Thunkable and the original person ---

OK - I can finally confirm that BLE transfer works both ways with ESP32 🙂 The key is really in setting right properties, and the easiest way for setting things up is 1. flashing the example BLE\_notify from ESP32 BLE Arduino folder in Examples 2. Connecting to the device name ESP32 (BLE block) 3. Using CHARACTERISTIC\_UUID from the example for Receive block. And basically you got it. Good luck and thanks for help Richard and the others! ---

Could you show an example of the receive UUID? I’m using either a romeo mini 2.0 or a HM-10, or a Nano BLE for modules and can transmit to the device from phone app, but can’t receive anything but “undefined” error message. ---

Have you tried with BLE\_notify example? ---

> [@neuheisser](#): > > CHARACTERISTIC\_UUID Thank for your sharing, I’m using HM10 connect with PC via USB to UART module. HM10 connect with my Android phone via Bluetooth. I can send string from phone to PC no problem, but could not receive string from PC. I’m using this UUID: 0000FFE1-0000-1000-8000-00805F9B34FB. Please advise any other UUID should be use? Thank you! ---

I believe this has something to do with the notification/indication characteristic and not the UUID listed for the HM-10 BLE. Wasn’t able to find a solution for this problem ---

Hi, can you please tell me which block i can use to get notify about device notifications such as call or messages. ---
