Hello oky understood.
Here's my idea but I require a bit of your cooperation

,
let's say you ship the dongle with a default firmware configured to a certain channel, baudrate, address,payload size etc.
We then define a simple protocol whereby the first received byte can contain two commands:
get nrf parameters: 0x11 payload empty but returns a structure
set nrf parameters: 0x23 payload full with the same parameter structure
In this way we avoid the annoying upgrading firmware issue both on my and your side.
If we combine this setup with the maniacbug mesh network support:

Unfortunately I don't have time to learn the 8051 mcu for the nrf so let me know
what ist he best way to proceed.
I could then buy some of the dongles and do some extensive tests.
I know that is some additional work but we don't have a deadline so feel free to do it
in your spare time.
PS
One of my other little projects was to port SWAP on Nordic chips.
