Its unclear that precompield BLE Mesh 2.0.1 demo does not run on nf52840 develboard

[Lukas_Simma]

Hello

For the BLE Mesh 2.0.1 demo i bought some nrf52840 develboards. Then i write the demo with "python scripts/quick_start/quick_start_demo.py" to the nrf52840 develboard and the demo do nothing. After some look around i realized that the demo is prepared only for nrf52832 boards..

For me thats no problem but for someone who is new to Nordic ...

I follow this page, and "Compatibility" say that nf52840 is ok.
   http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.meshsdk.v2.0.1%2Findex.html
And the light switch demo does not restrict to nrf52832 for the precompiled demo
  infocenter.nordicsemi.com/index.jsp

But look at BLE Mesh 1.0, see the restriction to the nrf52832 board 
(One PCA10028 or PCA10040 development board for the client.....)
infocenter.nordicsemi.com/index.jsp

Please add the restriction to the documentation. Maybe in the next Mesh SDK add a second script for nrf52840 develboards.

Thanks,
Lukas

Hi,

Thank you for reporting this issue, it is highly appreciated.

I have notified the team of this bug. It should either be stated clearly that the script only supports nRF52832 DK, or the script should be improved to support also the nRF52840. Exactly as you write, both nRF52832 and nRF52840 are supported. You can mix and match as much as you would like if you program the boards manually.

Regards,
Terje

Hi,

Thank you for sharing! Making a copy named quick_start_demo_nrf52840.py and change those four lines would be a very quick and easy way to support a set of nRF52840 DKs.

hello,

Apologies for being late to the 'party' on this... however both the current quick_start_demo.py and the proposed quick_start_demo_nrf52840.py scripts only support environments with single type NRF52 boards.

I did change the quick_start_demo.py script a little while back to support environments regardless of the make up of devkit boards.

soft_dev_hex52832    =  cwd + "./bin/softdevice/s132_nrf52_6.0.0_softdevice.hex"
provisioner_hex52832 =  cwd + "./bin/otime/light_switch_provisioner_nrf52832_xxAA_s132_6.0.0.hex"
client_hex52832      =  cwd + "./bin/otime/light_switch_client_nrf52832_xxAA_s132_6.0.0.hex"
server_hex52832      =  cwd + "./bin/otime/light_switch_server_nrf52832_xxAA_s132_6.0.0.hex"

soft_dev_hex52840    =  cwd + "./bin/softdevice/s140_nrf52_6.0.0_softdevice.hex"
provisioner_hex52840 =  cwd + "./bin/otime/light_switch_provisioner_nrf52840_xxAA_s140_6.0.0.hex"
client_hex52840      =  cwd + "./bin/otime/light_switch_client_nrf52840_xxAA_s140_6.0.0.hex"
server_hex52840      =  cwd + "./bin/otime/light_switch_server_nrf52840_xxAA_s140_6.0.0.hex"

Needless to say it's based upon determining the type of board 52832 or 52840 and then flashing the requisite hex files accordingly (see attached quick_start_demo-v2.py script)

def board_type_get(device_id):
    if (device_id[2] == "2"):
        return "52832"
    elif (device_id[2] == "3"):
        return "52840"
    else:
        return "00"
