I'm trying to set up communication between an nrf51422, and an nrf24l01+.
The nrf51 is supposed to be the PTX device, and the nrf24 the PRX device.
Communication from PRX...
I was learning GPIOTE using the example provided in SDK 9.0.0. (examples\peripheral\gpiote). The example only uses GPIOTE task and a timer to drive the task through PPI. ...
We have created a firmware and encrypted it with a private key and made it public. When we download it to the chip it's decrypted with a public key stored in the chip. Right...
I have about 200-300 sensors, each requiring to send data at around 0.5-1Kbps to a central node (coordinator/master node), what will be the network configuration/topology...
In SDK 8 for the nrf51422, notifications are always being sent as 20 bytes, regardless of p_len. The BLE_EVT_TX_COMPLETE event stores the proper number in tx_length, but the...
Hi everybody.
I am making an application which combine ANCS and UART on PC100028 (nrf51 SDK 9.0.0). This program worked properly. However when I add DFU service (dfu_dual_bank...
