GATT caching causing OAD to fail 

Devices affected:

• iOS 16.0.1, iPhone 14
• Android 13, Galaxy S22

Configuration:

• OAD on-chip
• CC2340R5
• SDK version: 7.10.00.32
• Public Address
• No pairing
• No Bonding

Steps to reproduce:

1. Flash 3 images : basic_ble_oad_onchip, basic_persistent, mcuboot
2. Open the mobile app 
3. Connect & attempt OAD

 
Workaround:
In the latest versions of iOS and Android, a caching feature was added for the GATT table, so when switching between the basic_ble_onchip application and persistent_app, the sending side does not re-request the updated table, the workaround that prevents the sending side from performing caching is this:

Inside common/Startup/osal_icall_ble.c delete these rows:

#if defined ( GATT_NO_SERVICE_CHANGED )
cfg_gapBond_gatt_no_service_changed = 1;
#endif

cfg_gapBond_gatt_no_service_changed has to be equal to 0
