I'm trying eval board with SPBTLE-1S module. I'm using BlueNRG-1 Navigator v 2.6.0. If I flash any demo application, no BLE service can be discovered on the phone (Nexus 5X, Android 7.1.1.)
E.g. BLE Sensor demo - DL3 shorty blinks after reset, then BL1 slightly flashes, so the chip is doing something, but no RF signal. (Previous chip TI CC2540 has communicated correctly, with the same phone.)
Have I missed something or is the chip broken?
