...to the Gateway and acts as a GATT server (custom profile) with the Gateway acting as a GATT client. At a minimum the GATT server receives commands from the GATT client to control its RGBY LEDs, and notifies the GATT client of the status of the button and the level of the device's battery. Optional auxiliaries on this device are an NFC card reader and an E-Paper display (EPD). When these auxiliaries are in use, the GATT server notifies the client of an NFC ID scanned after the button is pressed, as well as receives bitmap data from the client to update the EPD. The device must be optimized for maximum battery life (No less than 2200 hours between replacements) and will stand by in a low-power/sleep mode, waking at 1 second intervals to com...

Hello there We need a sample mobile application that I have detailed below. Platform: ios Subject: Gatt / Ble Service Sub Topic: Apple HomeKit Purpose: Sample application development Features The Iphone phone will broadcast a UUID that we have determined, from which we can receive a connection request over bluetooh. When a connection request comes up, it will write the mac address of the connected device on the screen. It will disconnect. It will broadcast a new UUID that we will determine over Bluetooth. Gatt characteristic read feature is not required, this feature will not be. If you have worked on Gatt and BLE services before, please contact for detailed information.

...form of a string of alphanumeric characters ranging from 3 to 35 characters. The IoT device uses an LM506 USB bluetooth module supporting dual mode (Classic and LE), with a class 2 TX output power and full speed USB 2.0. The device sending the commands will be developed separately and run on an iPhone, iPad, Android phone or tablet. It does not matter. That device will be the GATT Client and the IoT device will be the GATT server. So the code should be to initialize BT, set up the sockets and protocols and then respond and accept the connection request from the Client (iPad, Android, etc.) to establish the link, then deliver the commands. That's it. I am 90% there and have become quite versed on Linux tools like bluetoothctl, hciconfig, hcitool, etc. I can initializ...

NOTE: Accepting Quotes Only From USA We have a custom microcontroller hardware device that communicates with a mobile device via Bluetooth LE. All we need done for the first phase is to establish communication between the hardware controller (embedded C) and the mobile device (Android or Apple). GATT structure is very simple transferring only 2800 bytes in an array every 300 ms. We will supply hardware and schematics. Specifically, the hardware is a single board containing multiple identical 8 bit microcontrollers which share a 2 wire communication bus (CLK and DATA) and connects to a central Bluetooth module via a separate 2 wire connection. So the project includes 3 tasks: 1) The 2 wire communication bus protocol will need to be bit-bang in nature (hardware peripheral not avai...

The requested task is to be able to create a custom RPC call that has a to a remote server in between. The case scenario is as follows: An ESP32 device that is connected to internet and registered in and has the GATT service enabled A user, that has no internet access, but makes a RPC Call by bluetooth to the ESP32. The ESP32 will recieve this request (with custom data) and performs a simple HTTP Rest query to a remote server, depending on the server response, it should return some values directly to the GATT Connection. The main structure is done in MJS, the requierement is to be able to call the RPC from mJS and not C, althow C function can be used and called under ffi integration. Attached is the actual RPC handler. As you can see in the function, is async
