CC2541: I want to perform OAD using Android or iOS App, not using Btool or Bluetooth device manager with USB dongle

It seems TI Simplelink Starter App doesn’t CC2541 OAD now. You can try to get TI SensorTag Android App example code from

https://git.ti.com/cgit/sensortag-android

Hi YiKai Chen,

Thanks for the reply. If I download TI sensor Tag App from google play store then it will work ?? 

Actually I did that but still the same problem I faced with Simple link starter App.

I test latest SensorTag App and find it seems not support CC2541 OAD too. That's why I give you the example source code to do it by yourself.

Hey Yatin,

Glad this has been resolved. Feel free to post any follow up questions you have in a new post by clicking "Ask a related question".

Hi Ammar, 

This is not resolved yet. My App developer created the App for me as per the YiKai Chen file and when I'm trying to scan the device nothing is showing up whereas in my phone's bluetooth settings I can see the SimpleBLEPeripheral. 

I am also attaching the video for the reference.

Try to replace scanRspData, advertData, and attDeviceName with the following code to build and test again.

// GAP - SCAN RSP data (max size = 31 bytes)
static uint8 scanRspData[] =
{
  // complete name
  0x0A,   // length of this data
  GAP_ADTYPE_LOCAL_NAME_COMPLETE,
  0x53,   // 'S'
  0x65,   // 'e'
  0x6E,   // 'n'
  0x73,   // 's'
  0x6F,   // 'o'
  0x72,   // 'r'
  0x54,   // 'T'
  0x61,   // 'a'
  0x67,   // 'g'

  // connection interval range
  0x05,   // length of this data
  GAP_ADTYPE_SLAVE_CONN_INTERVAL_RANGE,
  LO_UINT16( DEFAULT_DESIRED_MIN_CONN_INTERVAL ),
  HI_UINT16( DEFAULT_DESIRED_MIN_CONN_INTERVAL ),
  LO_UINT16( DEFAULT_DESIRED_MAX_CONN_INTERVAL ),
  HI_UINT16( DEFAULT_DESIRED_MAX_CONN_INTERVAL ),

  // Tx power level
  0x02,   // length of this data
  GAP_ADTYPE_POWER_LEVEL,
  0       // 0dBm
};

// GAP - Advertisement data (max size = 31 bytes, though this is
// best kept short to conserve power while advertisting)
static uint8 advertData[] =
{
  // Flags; this sets the device to use limited discoverable
  // mode (advertises for 30 seconds at a time) instead of general
  // discoverable mode (advertises indefinitely)
  0x02,   // length of this data
  GAP_ADTYPE_FLAGS,
  DEFAULT_DISCOVERABLE_MODE | GAP_ADTYPE_FLAGS_BREDR_NOT_SUPPORTED,
};

// GAP GATT Attributes
static uint8 attDeviceName[] = "TI BLE Sensor Tag";

Hi YiKai Chen, 

I tested with the configuration you send, same result. Not showing in the App but showing in the phone's bluetooth settings.

If you run TI Simplelink Starter App on the same smartphone, can it scan your CC2541 BLE device successfully?

On Simplelink App, it is showing and connecting and by the way after changing it to sensor tag, I can actually see the sensor tag icon inside SimpleLink App and when I'm performing TI OAD service an error message is popping up saying CC254x is supported for OAD in this App.

I can only suggest you to debug the App code to see where it goes wrong.

Hi YiKai Chen, 

I tested with the SensorTag iOS App and OAD happened successfully on CC2541 keyfob hardware but on Android phone it is not happening.

It’s good to know you can use ios SensorTag app to do OAD test.

Hi Yatin,

It seems like there is something missing on your Android app side. Unfortunately, I do not have the expertise to assist in this area. Here's a related post that may help with the OAD part of the App.

Thanks Ammar N I will check the link you shared.
