Hi, I'm building code for a CYBLE-224110-00 (currently sitting on a CY8CKIT-042-BLE) using PSoC Creator 4.4 (4.4.0.80). My BLE Component is version 3.66 from the CyComponentLibrary.
The code I'm working with is basically Day 16 Authentication from the 100 Projects in 100 Days examples (https://github.com/Infineon/PSoC-4-BLE/tree/master/100_Projects_in_100_Days/Day016_Authentication). The one (critical I guess) thing I changed is that I enabled bonding in the BLE component configuration, and used similar code like in the Day 15 Bonding example to store the bonding information when there's a pending flash write (https://github.com/Infineon/PSoC-4-BLE/blob/master/100_Projects_in_100_Days/Day015_Bonding/BLE_Bondi...)
Overall the code works, but in my StackEventHandler I get an event with event code (decimal) 260 / (hex) 0x104. This is well outside the "normal" range of event codes (0 - 0xFF). Any idea what this event might be? It happens after the CYBLE_EVT_PENDING_FLASH_WRITE and after the bonding data is stored. Here the output / log from a "first" connection:

*edit* Doesn't seem to be related to storing the bonding information, here another reconnect (already bonded):
