I have the following issue with BlueNRG: when I try to use "INDICATION" to sending data from server to client I have ble crash (the BlueNRG stops to respond to any command) after a few indicate packet (50 - 60). When I use "NOTIFICATION" this problem is not appear. I have checked this issue in "Ble_chat" project (I have modified characteristic properties for "charUuidTX" from "CHAR_PROP_NOTIFY" to CHAR_PROP_INDICATE and set delay (1s) between sending packet) and this issue also has appeared. Maybe do you have any idea what could be the problem?
