The bluetooth low energy device going to measure the resistance of the circuit (the measured will record in his memory), the android App will connect to the BLE device and download the data from it. The battery of the bluetooth device will last a year. I need to get the design of PCB of the device. I need to get the app android I need to get the firmware of the chip BLE.

Hello Sir.. Electronic BLE Beacon with Data Logging Project Specification (Electronic) How It Works 1. Device shall periodically (Twice a day) read the resistant of the sensor and save it on nonvolatile memory on the device with Time Tag. Device shall have a Bluetooth 4.00 Low Energy connection for data download with any Bluetooth 4.00 enabled devices like Phones Tabs. Main Controller IC will send UID to phone via Bluetooth module as beacon. Main controller handles all controls and requests of both Real Time Clock and Bluetooth Module. All ICs shall be on Sleep Mode for energy saving, Those shall only activate at the request of Bluetooth connection or RTC Alarm Pin Activation. 2. Major electronic subsystems attached to Beacon Device a. Main Microcontroller b. Real Time Clock ( for Time keeping) (hereafter referred to as “RTC”) c. Bluetooth Low Energy Module Main Microcontroller 1. Atmega 328P MLF IC ( Datasheet : [login to view URL]) a. 32k Program Memory b. 1K EEPROM c. Serial Interfaces d. Internal 4MHz Oscillator 2. RTC and Bluetooth Module directly control 3. Battery Operated Device. 4. Power saving modes enabled. 5. Status LEDs / IO Controlling 6. Battery controller Bluetooth Low Energy Module 1. Texas Instruments CC2541 IC based module HM-11 2. Device Features a. CC2541 Bluetooth Chip Solution b. Fully Qualified Bluetooth V4.0 Ble c. Full Speed Bluetooth Operation with Full Piconet Support and Scatternet Support d. Incredible small s

Hello, I am interested in your project. I have experience on CC2541 and have development kit from TI as well. Please provide below details: 1. What is the dimensional restriction for the device? 2. At what time interval you will connect to this device and download the data? 3. At what time interval the resistance measurement should be kept? Thank you, Sam
