Hi Antonio,

Please take a look at this mail chain:

a BBC micro:bit with nRF51822 256KB flash and 16 KB RAM can support BLE mesh. Yes, it is stretch on a 16 KB RAM variant, but you can take a look at the output of “make rom_report” to fine tune/reduce RAM usages in your application.


Thank you Vinayak,
Got it working after deleting health and level server.

Memory region         Used Size  Region Size  %age Used
           FLASH:      100376 B       256 KB     38.29%
            SRAM:       16264 B        16 KB     99.27%
        IDT_LIST:         132 B         2 KB      6.45%

But after adding support for LOW POWER feature got RAM overflow again…

Memory region         Used Size  Region Size  %age Used

Since GATT (GATT_PROXY,PB_GATT,Peripherial) support is so memory hungry, can we use PB_ADV instead and do something like
remote provisioning ?

Is this feature supported ?
Trying to make something useful out of the NRF51, like a simple low power node mesh device.
But seems they are good only as a beacons for now ;(
Or perhaps someone can recommend the way to provision NRF51 node over the PB_ADV barrier ?
