#Nordic Semiconductor nRF51822 Firmware for Background Data Recording
Updating on https://github.com/scytulip/nrf51-back-rec
This firmware is designed for low-cost long-time low-power unattended data recording.
BLE Link could be intentionally enabled to transfer data. When a BLE connection is created, the firmware will report the data reading through BLE Heart Rate Monitor (HRM) service to the central device instantly. If a file transfer command is issued by the central device. The firmware will stop data recording and start the file transfer. After the transfer is finished, the central device should issue a resume command to restart data recording.
This demo version implements a MAXIM DS1621+ I2C interface temperature sensor as the data source for temperature collection. You can modify it for any other purpose.
Same issue. Digging found that Nordic UART Service "nus" isn't included in SDK6.1.0, but is in experimental project of SDK6.0.0, so I extracted only experimental\ble_app_uart from SDK6.1.0 (nrf51_sdk_v6_0_0_43681.zip):
Then copied ble_nus.c and ble_nus.h to this project:
It compiles OK now and connects with Andoid App nRF UART v2.0, it seems to run as describes but further testing required to confirm.
I'm trying to compile however it cannot find ble_nus.h in ..\peri\back_dat.c. Please let me know where I can find this. Thank you. I am using the correct SDK.
