CC1350: How to do OAD on cc1350?

Hello, thank you for viewing my question.

i am implementing a fire detection system with firmware update (ota) enabled.

i am trying to implement oad using RF(447Mhz) - not BLE

before registering this question, I implemented it according to the instructions in the link below.

(TI 15.4-Stack - Over the Air Download (OAD)) --- (A)

(TI 15.4-Stack - Linux Gateway Project Zero) --- (B)

https://dev.ti.com/tirex/explore/node?node=A__AA4oc9i.ZFkDjiqgYyXC0A__com.ti.SIMPLELINK_ACADEMY_CC13X0SDK__1FaRUBA__LATEST

the example code used is as follows:

client : bim_offchip

server : coprocessor

while implementing according to (A) and (B), when I entered the command to run the gateway, the output was different from the expected result. I found out that the examples (A) and (B) were based on CC13x2 & CC26x2, and I thought that the cc1350 I use should be implemented in a different way.

how can I do OTA from CC1350 to RF?(not BLE)

i am looking for examples and advice on implementation.

is only BLE-based OTA possible with the cc1350?
