Multi protocol, ble and thread support with free rtos

[ashish_shukla]

Hi all,

We have a running project with Nordic SDK on thread. 

Now, we are considering to include some ble functionalities in our application and use freertos to manage our application. We want few questions to be answered

1. Will OTA still work even if we use an RTOS?

2. Application size of a freertos example with multi protocol support for ble and thread is around 540KB. On top of that we need to write our application. In this case we don't have enough space to accommodate OTA as flash size is 1MB in NRF5240. Is there any workaround for the same with including external hardware?  

thanks

Hi Ashish,

1) Yes, OTA is OS agnostic.

2) You wont be able to do dual bank updates. But if you managed to fit the stacks, application and the bootloader, then single bank update should be possible.
