A mix of hardware and software questions.
We are working on a battery iBeacon for which we require some of the beacon parameters to be updated by a maintenance app (UUID, major, minor, Tx rate e.t.c). Originally we planned to update these parameters using a patch which was updated by SPOTA, but since your new beacon reference design I see uses now uses SUOTA. If possible I have some questions relating to this application:
1. When updating only a few parameters is SPOTA or SUOTA more suitable for this application and easier for develpment?
2. We planned to use external I2C memory for the patch which I am not sure of the patch size required, but do you have any approved I2C with smaller memory compared to the versions listed in AN-B-023 which are fairly high cost?
3. We are using the Expert Dev kit, but P0_5 is currently used for the serial debug. If using external flash, how do you configure the dev kit if using external SPI Flash and serial debug?
