Difference of basic configuration between "ble_app_uart" and "ble_app_template" in SDK 15.2.

[Zain Ali]

Hi,

I am a newbie and just started working on the nrf52840 board. I started by using the example "ble_app_uart" and implemented the I2C module to read IMU sensor data and it is working fine. Then I transferred my I2C code to "ble_app_template" and set the required configurations in the sdk_config module.

In the "ble_app_template" the I2C is working fine but I am getting the Nrf logs dropped message after few readings of IMU which I don't face in "ble_app_uart" project. I have set and matched the Log and clock configuration in sdk_config. I want to know is there any difference in configuration of the two projects. I am not using the BLE functionality in both example projects and they are as they were in default. I only implemented the I2C module (TWI).

Thanks,

Hi,

It's difficult to be certain without understanding the program flow in your application, but my guess would be that the idle_state_handle() which is where the logs are processed are called more often in the ble_app_uart example than in your template based project. Which means that the logs would be processed more often, resulting in logs not being dropped.

best regards
