I have a similar task. I am using BCM20736 modules. I would program module A (first BCM20736 module) with firmware via the uart. I would then like to have it (module A) replicate its firmware OTA to a second Module B (also a BCM20736). Module A would only update a second device when instructed. Is there any limitation in "replicating" firmware OTA between BCM20736 modules? All of this would initially not be using the secure process.
