LAUNCHXL-CC26X2R1: OTA question: old chip(Revision C) with old SDK(2.30) and new chip(Revision E) with latest SDK(2.40)

Lawrence Lin

Hi TI team,

I want to ask some questions about OTA.

1. I want to know whether I can use old chip(Revision C) with old SDK(2.30)(Coordinator) and new chip(Revision E) with latest SDK(2.40)( End-Device) to implement OTA.

Or I need to implement OTA by using the latest chip(Revision E) and latest SDK(2.40) to be a Coordinator and End-Device.??

2. What's example code that I can use?? The example code of zed_switch_ota_client(V2.40) to be a End-Device and the example code of zc_ota_server(2.30) to be a Coordinator??

3. what's differences between zc_ota_server and zc_switch_ota in the old SDK(2.30)??

Thanks

1. It should be no problem.
2. You choice looks fine.
3. I suppose zc_ota_server is connected to OTA server applicaiton on Windows to do OTA to other Zigbee device. I suppose zc_switch_ota can be OTA updated if your OTA server applicaiton on Windows connecting to zr_ota_server.

Hi YK,
I want to ask two more questions.
1. I knew the CC2652 need external flash to implement the OTA so that the End-Device of CC2652 need to connect a external flash.
But whether the Coordinator of CC2652(using the example code of zc_ota_server) also need to connect a external flash??
2. What's size of external flash that we need to use for OTA?

Thanks

1. No, zc_ota_server doesn't need to connect a external flash.
2. I suggest to use the same size at least as flash size of CC2652.
