merging ble_peripheral and freertos and twi example.

[mahesh gaonkar]

all set. while in linking stage i am getting

.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol nrf_sdh_is_enabled (referred from nrf_fstorage_sd.o).
.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol nrf_sdh_request_continue (referred from nrf_fstorage_sd.o).

errors. how to solve this ?

You need to define those symbols!

Take a look at one of the unmodified projects to see where they should get defined.

Most likely, you have omitted some sdk_config.h settings, and/or adding some source files to your project  ...

Hi,

These symbols are defined in nrf_sdh.c. Also, make sure to include nrf_sdh_ble.c nrf_sdh_soc.c as these are needed for forwarding of Softdevice events to various SDK modules such as fstorage. See the SoftDevice Handler library for more details. 

Edit: it's probably easier to merge TWI  into the ble_hrs_freertos example than it is to merge freertos and BLE into an example that doesn't use the Softdevice.

hi,

problem solved. 

it compiled. but now i am getting cortexM4 error while flashing to nrf52 development kit. but using the same s132 soft device , fresh ble_pheripheral example working. but merged one not working.

Have you changed the linker settings so the application starts above the Softdevice? The current memory layout is shown in 'options for target -> target' in Keil.

[mahesh gaonkar]

yes, i have changed as exactly in the ble_app_uart example
