Hi,
Whenever i call aci_gatt_clt_disc_all_primary_services() or aci_gatt_clt_exchange_config(),
the stack returns BLE_STATUS_INSUFFICIENT_RESOURCES (0x88).
What exactly is insufficient? Is it the heap size of the stack is just busy?
What adjustment do i need to make to solve this problem?
Some backgrounds of my firmware:
Heap is set to 0x800
Using data length extension
Using coded PHY (S=8)
Using extended advertising and scanning
