Migrate project using SDK14.1 S132 to use S140

[mike]

Hi

Im trying to figure out how to migrate my quite large older project from  and softdevice s132 to using s140 (SDK14.1 )in order to experiment with long range.

Besides changing header- and hex-files I think I need to change some Ram and flash setting is that correct? Which settings exactly do I need to change? 

(using arm gcc not SEGGER)

You are correct in what changes you need to make, but you will also need to:

Replace these files:

• /components/toolchain/gcc/gcc_startup_nrf52.S -> /components/toolchain/gcc/gcc_startup_nrf52840.S
• /components/toolchain/system_nrf52.c -> components/toolchain/system_nrf52840.c

Replace these defines and assembler flags:

• BOARD_PCA10040 -> BOARD_PCA10056
• RF52832_XXAA -> NRF52840_XXAA
• S132 -> S140

Add these defines and assembler flags:

• FLOAT_ABI_HARD

Remove these defines and assembler flags:

• NRF52_PAN_74
• NRF52

Addtionally in the linker script I see that there are some sections which have "SORT()" added on nRF52840, which may be necessary for you as well.

If your implementation is not changed from the default too much it may be simpler to copy a Makefile and linkerscript from the SDK and use that with whatever changes you need.

ok its now building but the advertising does not seem to be working although not getting an error(scanning with the nrfConnect app)

have set the adv_params to be 1MBPS on physical properties so it should not be a problem

EDIT : when we set scannable and legacy_pdu  to 1 it seems to be working. But we are having difficult time finding out what these parameters do exactly

Ive read that legacy PDU should be set when using advertising extension but I dont recall setting this explicitly anywhere. Where is this done?

Hi,

Sorry for the late reply.

You may have already seen this, but here is the migration guide for getting from SDK 14 to SDK 15. If you have a look at the section regarding "Advertising Extensions using the Advertising module" you will find the statement "Make sure ble_adv_extended_enabled = false; to preserve advertising functionality similar to older SDKs."

You have probably inadvertently enabled the advertisement extension when porting the code. Ensure that API call "sd_ble_gap_adv_set_configure" is done with something like this as the ble_gap_adv_data_t parameter:

.....adv_params.properties.type = BLE_GAP_ADV_TYPE_CONNECTABLE_SCANNABLE_UNDIRECTED;

When you have everything working as intended, you may re-enable the advertisement extension if you want and set up everything correctly to use it. I am just recommending getting the port working as it used to first.

Best regards,
Rune Holmgren

Rune,

Can you please update the link to migration guide for SDK14 to SDK 15 ... it's broken.

Thank you.
