Updating RN4871 Firmware
I have been doing some research on how to update the firmware of the RN4871 and have come up with 2 possible approaches.
1. There is some mention of over the air firmware updates, however, I wasn't able to definitively find out how to do this. It would seem some level of intervention from Microchip would be needed to accomplish this.
2. Have my host MCU which is connected to the RN4871 act as a USB to RS-232 device so that the software to update the RN4871 could be used to select the comport the MCU was assigned. In this example the MCU would just act as a USB to Serial bridge between the computer and the RN4871.
Has anyone been able to achieve updating a RN4871 in their product and not on a pictail?
I'm thinking approach #2 outlined above is probably the most sound solution and has the highest chance of success, any thoughts?
