I am really struggling getting anything to work on my revision 1 module and as it has nothing connected at this moment all I can use is BLE or UART to observe any function...
Hi,
I would like to change the the advertising interval of the beacon kit in the sample ble_app_beacon app; however, I could not figure out where this parameter is. I see...
Hi,
I want to connect a rotary encoder.
So I have 2 pins of the nrf51822 connected to the encoder and I have to check which one change first to increase or decrease the...
So there seems to be a conflict between the TWI and the Softdevice. My I2C communication works over TWI fine in isolation but when i try to send data over ble the TWI doesnt...
I am using the nRF24le1 in Enhanced Shockburst mode.
The datasheet describes how it is possible to upload acknowledge packets, W_ACK_PAYLOAD, to the TX FIFO. And then the...
Hello,
I need to get RSSI with the NRF51422 (pca10031, S110), but i don't want to connect with a central device (i.e. Smart Phone). The central device should scan for bluetooth...
We tried to pair with and connect to nRF51822 DK running HTM app with SONY VAIO fit15e NB and always fail as we did the following steps.
We also tried some devices like ASUS...
Hi,
I just replaced the BLE chip in my board from CC2540 to nRF51822. I simply want to know how to configure the interrupt on a pin as well as rising/falling edge interrupts...
