nrf52-ble-multi-link-multi-role SES configuration issues

[jinvers]

Hello,

I am using SES environment with nRF Connect SDK 1.9, SoftDevice S140 and nRF5_SDK_17.1.0 to clone the nrf52-ble-multi-link-multi-role example on Github (https://github.com/NordicPlayground/nrf52-ble-multi-link-multi-role/issues) with the idea of using it a a basis for a new development.

The first step I'm trying to do is just testing the ble_aggregator\pca10056\s140\ses\ble_aggregator_pca10056_s140.emProject. I open this project usign SES environment. When I Build the project I get the next error in the compilation of main.c

nrf_ble_qg.h: No such file or directory

I have added the next line in Project\Options\Common\Preprocessor\User Include Directories:

../../../../../../../components/ble/nrf_ble_gq

When I build the Project again there are the next errors:

So it looks like the NRF_BLE_GQ is not enabled.

I have added in the sdk_config.h file the next lines:

// <e> NRF_BLE_GQ_ENABLED - nrf_ble_gq - BLE GATT Queue Module

//==========================================================

#ifndef NRF_BLE_GQ_ENABLED

#define NRF_BLE_GQ_ENABLED 1

#endif

// <o> NRF_BLE_GQ_DATAPOOL_ELEMENT_SIZE - Default size of a single element in the pool of memory objects.

#ifndef NRF_BLE_GQ_DATAPOOL_ELEMENT_SIZE

#define NRF_BLE_GQ_DATAPOOL_ELEMENT_SIZE 20

#endif

// <o> NRF_BLE_GQ_DATAPOOL_ELEMENT_COUNT - Default number of elements in the pool of memory objects.

#ifndef NRF_BLE_GQ_DATAPOOL_ELEMENT_COUNT

#define NRF_BLE_GQ_DATAPOOL_ELEMENT_COUNT 8

#endif

// <o> NRF_BLE_GQ_GATTC_WRITE_MAX_DATA_LEN - Maximal size of the data inside GATTC write request (in bytes).

#ifndef NRF_BLE_GQ_GATTC_WRITE_MAX_DATA_LEN

#define NRF_BLE_GQ_GATTC_WRITE_MAX_DATA_LEN 2

#endif

// <o> NRF_BLE_GQ_GATTS_HVX_MAX_DATA_LEN - Maximal size of the data inside GATTC notification or indication request (in bytes).

#ifndef NRF_BLE_GQ_GATTS_HVX_MAX_DATA_LEN

#define NRF_BLE_GQ_GATTS_HVX_MAX_DATA_LEN 16

#endif

Rebuilding the Project it appears the next error compiling main.c:

‘NRF_BLE_GQ_QUEUE_SIZE’undeclared here (not in a function)

I have added in the sdk_config.h the next lines:

// <e> NRF_QUEUE_ENABLED - nrf_queue - Queue module

//==========================================================

#ifndef NRF_QUEUE_ENABLED

#define NRF_QUEUE_ENABLED 1

#endif

 

#ifndef NRF_BLE_GQ_QUEUE_SIZE

#define NRF_BLE_GQ_QUEUE_SIZE 10

#endif

Rebuilding the Project it appears a new error compiling the main.c file:

'NRF_BLE_GQ_BLE_OBSERVER_PRIO' undeclared here (not in a function); did you mean 'NRF_BLE_ES_BLE_OBSERVER_PRIO'?

And here I have stopped. What I am losing? I though replicating the example should have been easier. Please, any suggestion?

Thank you in advance.

Hello Joel,

This example requires nRF5 SDK 15.2.0 to build. It has not been ported to SDK 17.1.0.

Hi Vidar,

What are the main differences and issues I should consider to make the porting to nRF5 SDK 17.1.0?

Or is there any other multi-link and multi-role example in nRF5 SDK 17.1.0 with the same functionalities?

Regards,

Joel

Hello Joel,

I ported the aggregator project to nRF5 SDK 17.1.0, please see attached. You can see the changes I made in the included port_sdk17.diff file. I expect it should work, but I have not tested it with multiple nodes.

Hi Vidar,

Great. Many thanks! I will check it.

Hi Vidar,

Thank you again.

I have tested up to 3 nRF52840-DK boards using the ble_app_blinky example. They work after configuring correlated device names. I have also tested using the BLE Multi Link Demo phone app with an older Android version (it doesn't work with some new versions).

My next step is testing the multi-link-role solution using the NUS service with these same 3 nRF52840-DK boards as NUS peripherals. According to the information I have found it's suppodes this should work. Although I have seen in the code that it will be necessary to enable the different define in the sdk_config.h file. Do yo have any other suggestion? Thank you in advance.

Best Regards,

Joel

Hi Vidar,

I would say that the NUS service was not completely introduced. I think there's more job to do to discriminate the type of devices connected and introduce the necessary ble_nus_xxx functions and management of the events and handles.

Hi Vidar,

I have now the multi-link-multi-role application able to aggregat multiple devices running ble_app_blinky or ble_app_uart with NUS services. However, I cannot only exchange data through terminal connection between the central multi-link board and one of the NUS devices. I have to modify the program as to select the NUS device to  which connect selectively. Please, any suggestion?

Thank you in advance.

Joel
