From: Pat Thoyts Date: Sat, 17 Oct 2015 20:30:39 +0000 (+0100) Subject: Implemented BTLE and normal nRF24 message with temperature and LCD display. X-Git-Url: http://privyetmir.co.uk/gitweb.cgi?a=commitdiff_plain;h=e3c89a1a22cf8b01891bb962a5c774f544cf8b50;p=arduino%2FnRF24_BLE_Temperature.git Implemented BTLE and normal nRF24 message with temperature and LCD display. While waiting for the next DS18B20 conversion we transmit the last temp reading over channel 85 to the IoT hub. The LCD display shows temperature and humidity and the Bluetooth beacon transmits the temperature. Included the Atmel Studio project file (used with Visual Micro Arduino support plugin). --- diff --git a/.gitignore b/.gitignore new file mode 100644 index 0000000..b9e61c8 --- /dev/null +++
