jksoft | 0:76dfa9657d9d | 26 | Instantiates a new GapAdvertisingParams instance |
jksoft | 0:76dfa9657d9d | 27 | |
jksoft | 0:76dfa9657d9d | 28 | \param[in] advType |
jksoft | 0:76dfa9657d9d | 29 | The GAP advertising mode to use for this device. Valid |
jksoft | 0:76dfa9657d9d | 30 | values are defined in AdvertisingType: |
jksoft | 0:76dfa9657d9d | 31 | |
jksoft | 0:76dfa9657d9d | 32 | \par ADV_NON_CONNECTABLE_UNDIRECTED |
jksoft | 0:76dfa9657d9d | 33 | All connections to the peripheral device will be refused. |
jksoft | 0:76dfa9657d9d | 34 | |
jksoft | 0:76dfa9657d9d | 35 | \par ADV_CONNECTABLE_DIRECTED |
jksoft | 0:76dfa9657d9d | 36 | Only connections from a pre-defined central device will be |
jksoft | 0:76dfa9657d9d | 37 | accepted. |
jksoft | 0:76dfa9657d9d | 38 | |
jksoft | 0:76dfa9657d9d | 39 | \par ADV_CONNECTABLE_UNDIRECTED |
jksoft | 0:76dfa9657d9d | 40 | Any central device can connect to this peripheral. |
jksoft | 0:76dfa9657d9d | 41 | |
jksoft | 0:76dfa9657d9d | 42 | \par ADV_SCANNABLE_UNDIRECTED |
jksoft | 0:76dfa9657d9d | 43 | Any central device can connect to this peripheral, and |
jksoft | 0:76dfa9657d9d | 44 | the secondary Scan Response payload will be included or |
jksoft | 0:76dfa9657d9d | 45 | available to central devices. |

jksoft | 0:76dfa9657d9d | 54 | Advertising interval between 0x0020 and 0x4000 in 0.625ms units |
jksoft | 0:76dfa9657d9d | 55 | (20ms to 10.24s). If using non-connectable mode |
jksoft | 0:76dfa9657d9d | 56 | (ADV_NON_CONNECTABLE_UNDIRECTED) this min value is 0x00A0 |
jksoft | 0:76dfa9657d9d | 57 | (100ms). To reduce the likelihood of collisions, the link layer |
jksoft | 0:76dfa9657d9d | 58 | perturbs this interval by a pseudo-random delay with a range of |
jksoft | 0:76dfa9657d9d | 59 | 0 ms to 10 ms for each advertising event. |
jksoft | 0:76dfa9657d9d | 60 | |
jksoft | 0:76dfa9657d9d | 61 | \par |
jksoft | 0:76dfa9657d9d | 62 | Decreasing this value will allow central devices to detect |
jksoft | 0:76dfa9657d9d | 63 | your peripheral faster at the expense of more power being |
jksoft | 0:76dfa9657d9d | 64 | used by the radio due to the higher data transmit rate. |
