https://devzone.nordicsemi.com/f/nordic-q-a/485/nrf2740-rdyn-low-after-resetI am trying to hook up nRF8001 to TI MSP430F663x via nRF2740 module. All inputs seems to be controlled properly. Once I release the nRF8001 RESET line, RDYN goes low instead of expected high. Toggling REQN does not change RDYN status.

After a reset it will send a device started event to let you know which state it is in (setup or standby). This event will look like this: 0x01 0x04 0x81 0x02 0x00 0x02</p> <p>Where: 0x01 = Debug byte, discard this 0x04 = Length 0x81 = Device started event 0x02 = Setup state 0x00 = No HW error 0x02 = 2 available data credits</p> <p>Best regards, Runar</p><div style="clear:both;"></div>
