I am connecting to a remote peripheral and am experiencing sometimes disconnection with reason 13. "Peer failed to respond to ATT value indication" can someone explain what this error means and why is it caused? I believe that I'm not "acking" an indication sent by the remote peripheral to me. but how is ack on indications done in swift? thanks in advance

hi, I am developing an accessory device which iphone connects to over BLE. meaning the accessory device is a peripheral and the mobile is central. I would like to enable the user to rename the GAP name of the accessory via IOS bluetooth settings. As seen in the link below. I have verified that I have write permissions for the gap name charecteristic on the accessory. I connect to the peripheral, press "i" on IOS bluetooth settings but am unable to rename (as if I have only read permissions). what am I missing? what else need to be configured? Is this option only available for bluetooth classic devices? thanks alot in advance! https://www.businessinsider.com/how-to-change-bluetooth-name-on-iphone
