Hi,
I'm using nRF5 SDK v15.0 with S132 v6.0. I have two questions:
1. I use the ble_app_uart example. We want to use high UART baud rate, so I change it to 1M baud rate...
The project I am working on stores information in SRAM while it waits for the radio to get in range and transmit data.
I want to know if I can put items in SRAM buffer that...
I'm trying to learn the DFU process and how to include it in a project under development using SDK 15 and the nRF52 DK. I programmed the DK with the S132 Softdevice and the...
