CC2340R5: OAD update using IOS custom App

Abinesh Rajendran

Part Number: CC2340R5

Hi team

We are using the CC2340R5 and developing a custom FOTA (Firmware Over-The-Air)IOS application.

Currently, we are facing an issue. We have flashed MCUboot, basic persistent, and basic BLE OAD images onto the device.

On iOS, we successfully connect to the application layer and send 0x01 to the FFD0 service, after which the device transitions to the persistent layer. However, after reconnecting, we are still able to see only the application layer services. We are not able to find the FFC0 OAD service, which is required for uploading the firmware.

Could you please suggest how to resolve this issue?

Thanks and regards

Hello Chandra,

Thanks for reaching out.

Please take a look at this training material if you have not already:

Bluetooth Low Energy - Over the Air Download (OAD) Fundamentals: https://dev.ti.com/tirex/explore/content/simplelink_academy_for_low_power_f3_sdk_9_14_00_02/_build_simplelink_academy_for_low_power_f3_sdk_9_14_00_02/source/ble/cc2340rx_06_oad_fundamentals.html

How to Add Bluetooth Low Energy (LE) Over the Air Download (OAD) to Basic Example: https://dev.ti.com/tirex/explore/content/simplelink_academy_for_low_power_f3_sdk_9_14_00_02/_build_simplelink_academy_for_low_power_f3_sdk_9_14_00_02/source/ble/cc2340rx_10_add_oad_basic.html

Please also refer to the on-chip OAD example inside the SDK for reference on how to implement it: <SDK>\examples\rtos\LP_EM_CC2340R53\ble\basic_ble_oad_onchip

Based on what you mentioned, my guess is that you are not starting the OAD Service, app_main.c -> OAD_start();

It could also happen that your custom APP is not showing those services, can you check with the SimpleLink Connect App and see if they are detected?

BR,

David.
