advertising during connection [SDK12 S132 nRF52]

[Oleg]

hi all!

if I restarting advertising with BLE_GAP_ADV_TYPE_ADV_NONCONN_IND during CONNECTION occur sd_ble_gap_adv_start(..) returns error = 0x07 (NRF_ERROR_INVALID_PARAM)

if I restarting with any other during connection, it returns error=0x12 (NRF_ERROR_CONN_COUNT)

IS IT POSSIBLE to use Advertising during CONNECTION ?

Thanks!

What have you set the advertising interval to? Notice that minimum advertising interval for non connectable mode is 100 ms.

Oleg,

No it's not possible to use advertising during a connection unless you allow multiple simulations connections to your peripheral. The advertising state and connection state our mutually exclusive states.

That's not correct. It is possible, and has been possible for many versions of the softdevice, to be in connection as a peripheral and advertise non-connectably. And non-connectable was what the original poster tried, however he must have another parameter wrong hence the error.

it it not possible to be in connection and advertise connectably, but that wasn't what he was trying to do.

dear Jorden! you are right, thanks you!

In SDK 6.1, on SoftDevice 7.1 I noted that the minimum is in fact 152.5msec not 100msec. So your minimum will be dependant on your Stack version and SDK version.
