Timestamp problem

[mani]

Hi team,

I am using sdk 12.1.0 and ble_app_hrs_c example.I enabled #define NRF_LOG_USES_TIMESTAMP 0 to 1 and iam usng nrf51822 dongle.my program gets hanged.I need to print the timestamp.I am unable to view the data from serial.please tell me what is the problem??

Hi,

With the NRF_LOG_USES_TIMESTAMP functionality the user can create his own timestamp function. If you have enabled NRF_LOG_USES_TIMESTAMP, and have not provided the timestamp-function, initialization will fail with error NRF_ERROR_INVALID_PARAM.

Note: Most terminal programs have their own timestamp-functionality you can enable to get timestamps. In e.g. Termite you can enable timestamp in “Settings” -> Plug-ins.

A quick and probably dirty way to get timestamps working.

Copy counters.c and counter.h from examples/ble_central_and_peripheral/experimental/ble_app_att_mtu_throughput/ into your project.

Then make the following code changes. Assumes using pca10040 and armgcc. But should be similar for other setups.

Note counters.c is setup to count in 10ms intervals.

Hallo, this modifications that I need to do it in the makefile or in the main code?

Hi DavidC,

Q: this modifications that I need to do it in the makefile or in the main code?

A: If you are using a makefile(you are in fact usign armgcc), you need to apply changes in both main code and in the makefile. All changes needed is covered in the patch snippet above.
