    We have a nRF51822 BLE perihperal firmware in Embedded C (32-bit ARM Cortex M0 CPU) that is working and we want to implement this feature: Allow bonding to other devices only when a button is pressed: advertise with whitelist filtering except when the button is pressed. Than I advertise to accept any connection for 30 seconds. After it is bonded it can connect using whitelist. something like this: https://devzone.nordicsemi.com/question/28073/how-to-allow-bonding-when-a-button-is-pressed/ attached a Nordic example using ...

    I would like to develop answer/hangout call functionality on HID over GATT. I'm developing a BLE gadget(multimedia and answer/drop) using a Nordic nrf51822 SOC and HID over GATT to avoid deploy a custom app for Android. I have no issues about multimedia control but answer/hangout call functionality is a pain in the ass!!. There is a current firmware(Keil uv4) that works ok with IOS but Android don't let me answer/respond with same ...

    Hello, We developed a motion controller based on Altera Cyclone 2 FPGA CPU. We are looking for a developer who can write parts of the CPU of the controller. The CPU code is written in ANSI C for embedded systems and the IDE is NIOS II. The controller is motion controller. The controller includes digital and analog I/O, encoder readings (incremental, SSI, BISS, Analog Volt) and Hall sensors, communication protocols like RS232, CAN, SPI. Currently we want to implement ...

    I want to have a simple BLE scanner, running on nrf51822 Hardware, using Nordic SDK 7.2 or 8.0. It should only scan continuously for iBeacons and report on it's Serial Interface (using SIMPLE_UART on the default pins Pin 9 and 11) the Beacons found. It should report the whole 128 BIT UUID, Major, Minor and rssi. Using the UART I want to be able to issue the commands "start", "stop", and "restart" to the Nordic Chipset.I ...

    An activity monitor (i.e., pedometer) on existing hardware, which consists of a Nordic Semi NRF51822 + accelerometer, capacitative button, charge controller, buzzer, and display. Hardware is already built. Have to work with us to define a sensible bluetooth LE service, then implement it. Device must support OTA firmware upgrades, Apple's ANCS notification service, and BLE bonding. We'll be integrating the device into an existing Android/iOS app, which already uses BLE to talk to a number of different ...
