I am trying to build the following: An ESP8285 is connected to a LiPo via an LDO (3.3V). A SHORT button press should latch power to the ESP8285/ESP8266. The problem is that the latch circuit is always on, even when the button is pressed. The circuit needs to fixed so that: 1) The short button press latches power to the ESP. (Power usage should then be 0) 2) GPIO16 or another GPIO, can unlatch...

This letter presents an antenna system for mobile devices with an unbroken metal rim. By utilizing the characteristic mode analysis for the unbroken metal rim, efficient MIMO operation can be achieved. The design is based on antenna cluster technique that uses several coupled elements that are used to efficiently excite the modes of the rim. Non-resonant antenna elements and matching networks are ...

The LimeSDR-USB allows to either transmit signals at once or schedule them. In all cases the samples must be passed from the host to the device at each call, which can take time due to the USB speed and latency. We would like to be able to just tell the device to transmit a specific type of signal, either at once or at a specific timestamp, without passing the samples each time. The different sig...
