I was trying to implement 2 different UART connection parameters so I decide to use re-initialization.
My initial parameters included APP_UART_FLOW_CONTROL_LOW_POWER...
I'm trying to use the nrf8001 (and arduino) to send MIDI (musical note data) to Mac OSX. According to the Apple developer site the midi profile requires that the characteristic...
what does it mean the VTG led turn red ? but it has no bad effect to my project. In addition, I find a strange phenomenon. I use three 1.5v battery to power my board. The...
I ran the ble_aci_Tranport_layer_Verification.ino sketch from the Nordic BLE library and I get no output to the serial monitor after "nRF8001 Reset Done" is displayed. I think...
Hi nordics!
First of all, thanks for answering my questions before.
Now, I want to generate a clock(48 pulses) with 200us width.
However, sometimes the width of...
