Choosing the Central...https://devzone.nordicsemi.com/f/nordic-q-a/10916/choosing-the-centralHi, Can a peripheral choose among multiple central? Consider a situation where I have a 3 centrals. Lets say CentralA, CentralB and CentralC with, CentralA - High connetction priority... CentralB,CentralC - Low connection priority...

Surely my advertising parameters were less than 100ms that probably can be the reason..I will check on that. Thanks..</p><div style="clear:both;"></div>RE: Choosing the Central...https://devzone.nordicsemi.com/thread/40800?ContentTypeID=1Fri, 18 Dec 2015 10:14:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b49b7082-78e3-46fa-9880-1520ec0aae2bPetter Myhre<p>It would be helpful if you actually included the parameters you are using. What advertising interval are you using? It has to be 100 ms or more. Could that be the the reason why you get an error?</p><div style="clear:both;"></div>RE: Choosing the Central...https://devzone.nordicsemi.com/thread/40798?ContentTypeID=1Fri, 18 Dec 2015 09:39:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:79f53084-75da-48c7-a9e6-1c810928bdd5chirag<p>Are there any advertisement parameters that needs to be changed. I did try to start advertisement with BLE_GAP_ADV_TYPE_ADV_SCAN_IND, but the sd_ble_gap_adv_start() function returned with error code:NRF_ERROR_INVALID_PARAM. So what other advertisement parameters are to be changed and What are their hard limits?</p> <p>Thanks Again!!</p><div style="clear:both;"></div>RE: Choosing the Central...https://devzone.nordicsemi.com/thread/40797?ContentTypeID=1Fri, 18 Dec 2015 09:33:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:db74ce33-7ec6-478e-b30e-21e2ced50c99Petter Myhre<p>Our peripheral SoftDevices support non-connectable advertising while in a connection. So you can use the BLE_GAP_ADV_TYPE_ADV_NONCONN_IND or the BLE_GAP_ADV_TYPE_ADV_SCAN_IND advertising types while in a connection.</p> <p>If you use BLE_GAP_ADV_TYPE_ADV_SCAN_IND central A can send scan requests, and the peripheral will get the BLE_GAP_EVT_SCAN_REQ_REPORT event. You can use this event to detect if Central A is active, if it is, you disconnect from Central B, and connect to Central A.</p><div style="clear:both;"></div>
