I have an nRF52832, coding with SEGGER and the SDK 14.2.0. I'm trying the ble_peripheral/ble_app_uart example (although I get similar results with the other BLE examples). I can build and run it, and I see a few debug messages. The nRF Connect app sees the advertising, but when I go to connect, there is a 40 second delay, and then GATT_CONN_LMP_TIMEOUT. But if I load a hex file built from the same source on a colleague's machine, it works. We both started from the same VM image. I have to assume I have a configuration problem, but I don't know where to look.
