Part Number: CC2640

Tool/software: TI C/C++ Compiler

We have two requirements from one of our client regarding BLE-

o Scan tags.

o Pair with a BLE device and get information.

We have few queries regarding this implementation:

1. For this implementation we need to keep BLE in (Peripheral + Observer Mode) or (Peripheral + Central Mode).?

(Note: we have no option to replace the BLE part Number)

2. We have already shipped the boards to our customer with SimpleBlePeripharal OAD image.So if we change the application code with latest requirements(scanning) will this be supported by the STACK of previous OAD.

(Note: Please let us know about memory constraint also)

Can you please check this and let us know what can we do in this case?

Since you need to pair with BLE device, you should use peripheral+Central multi-role application. Try to refer to processors.wiki.ti.com/.../Cc2640_MultiRole_Demo

Hi chen,

But i need to see scanned tags (What other BLEs advetising).For that observer is not fine?

You can scan tags using central role scan instead of observer. According to your descriptions on application, it seems you only need central role.

Hi,

1. I want to scan the tags(what other ble are advertising) and brodcast my BLE name ,Pairing and send/RX information on ble .
2. We have already shipped the boards to our customer with SimpleBlePeripharal OAD image.So if we change the application code with latest requirements(scanning) will this be supported by the STACK of previous OAD.

If you need broadcast BLE name ,Pairing and send/RX information on BLE, multi-role (Peripheral + Central) should work for your application.

What about OAD on peripheral OAD can we do Central + Peripharal OAD?

0 YiKai Chen over 8 years ago in reply to vidushi jain

Guru 735695 points

I think you can do OAD from doing peripheral connection.

Hi,

BLE Device is having OAD Application & stack Image of SimpleBLEPeripharal and now we have added central part in application so we need not to change in stack?
Will new application of multi role work with older SimpleBLEPeripharal OAD stack?

0 YiKai Chen over 8 years ago in reply to vidushi jain

Guru 735695 points

I suppose you have to change Stack part too.

If we want scanning for advertisement then we can use observer?

Can u explain the difference between observer and Central?

Hi Chen,

We are using OAD target sample code as image A in ble device will it support any application on top of it whether SimpleBLEPeripharal or SimpleBLEPeripharal_Central as image B?

observer is unconnectable. Whereas central can connect too to the slave which are advertising.

Hi All,

When we are trying to change an application with oad feature as per the steps given in developers guide we are getting error while doing OAD in BLE device monitor i.e OAD IMe.AGE REJECTED

Can anyone suggest how can we solve this issue?

Hello,

We have an errata guide posted at processors.wiki.ti.com/.../CC2640_OAD_User's_Guide

This will explain how to use BTool to perform an OAD. There is an improved OAD guide hosted here:

software-dl.ti.com/.../oad.html

Note that the guide above applies to CC2640R2F, but most of the topics within the OAD concepts section also apply to CC2640 as well.

The main reason why images are rejected is due to the candidate metadata being sent being unsatisfactory by the device. This is done in: OAD_imgIdentifyWrite
