There is a difficulty in programming using MDBT42Q-512KV2 module.

Hello

I am programming using the nrf52832 module 'MDBT42Q-512KV2' in SDK v17.0.

This works well without any problems in the example ble_app_blink.  However, the BLE is not working on the ble_app_uart and the ble_app_hrs.

When I debugged them, they all seem to have a problem with the log_init. Then is this a Softdevice problem?

Can I get a solution to this problem?

Thank you!

Hi,

Are you using an external low frequency crystal or the internal RC oscillator? Have you configured the config file appropriately if the latter is the case? 

regards

Hello, Jared .

I found the answer to this problem on a different ticket.
Corrected by adding 'nrf_gpio_cfg_input (RX_PIN_NUMBER, NRF_GPIO_PIN_PULLUP);' to the bottom of 'uart_init()'.

Thank you.
