Looking for someone skilled in BLE communications that can also program applications to communicate from a device(preferably iphone) to a BLE module. Knowledge of custom PCBA design is also required to design an integrated BLE module to fit the product packaging space. Overall objective is to allow a user to connect to the BLE module to perform tasks such as distance tracking between the two devices via RSSI and turning on/off a piezoelectric buzzer to assist with nearby location tracking. An iphone deploy-able application will also need to be developed to execute commands between the device and BLE module.

Actually it's basic functionality provided by Core Bluetooth. As soon as a Peripheral is discovered during the scanning, the Central delegate receives the following callback: (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI This call notifies the Central Manager delegate (the view controller) that a peripheral with advertisement data and RSSI was discovered. RSSI stands for Received Signal Strength Indicator. This is a cool parameter, because knowing the strength of the transmitting signal and the RSSI, you can estimate the current distance between the Central and the Peripheral. So, you can use the distance as a filter for a given service: only if the Central is close enough to the Peripheral, then your app does something. The RSSI value allows you to estimate the distance, create virtual fences and can also be used to zero-in on a BLE device by comparing the new RSSI measurement to the previous one. The theoretical relationship between RSSI and distance is something like this: RSSI[dbm] = −(10n log10(d) − A) where d is the distance and A is the offset which is the measured RSSI 1 meter point away from the BLE device. In this regard, I'm very skilled with the matter of accuracy/rssi/proximity with iBeacons and I really really think your goal can be achieved easily.

Hello,sir. How are u? iOS senior developer is here. I've just read your job post and much interested in your project. I have been creating high quality and excellent iOS and Android apps for 6+ years using Swift, Objectiv-C, Java. Here are some links to web& mobile apps which are developed by me. I'm expert in Geo-location, GPS tracking, Payment gateway integration, and Social media integration such as Facebook, Twitter and so on. I have good experiences in Firebase, Twillio Api, QuickBlox, AWS and so on. I can also develop backend apis using PHP(Laravel, Codeigniter), NodeJS, Python, as well as web portal including admin panel. I've rich experiences to work with various 3rd-party services and APIs to integrate them into existing and new applications to extend required functionality. The important thing is that I'll work on your time zone for the good communication. If you choose me, you'll never be disappointed in me, and I'll do my best. I can provide daily update for the project status.
