I have bought a Tayio Yuden EYSGJNZWY Bluetooth module, which is in fact just a Nordic's nRF51822 (256KB Flash and 32KB RAM) with added antenna. Tayio's files say that the module is factory preflashed with S120 V2.1.0 SoftDevice firmware EYSGJNZWY datareport - check p.6, s . This is my wiring schematic: On module power up there is no bluetooth advertising at all. I have tried sending AT commands via UART to see if it will return anything, but there was no response. Then I flashed it via SWD (OpenOCD) with S110 ble_beacon .hex precompiled example from Nordic's website - still no advertising or any sign of life AT ALL. What am I doing wrong?

From which SDK is this S110 ble_beacon .hex? Where did you find it? Did you flash a SoftDevice as well? Which one? Was it compatible with the application firmware?
