nrf52811 custom board - example code

ashokr.com

Hi All,

I have designed my custom pcb board for nrf52811. With the Jlink the IC is detected in visual studio code also it gets programmed. But i did not see its working when i use basic bluetooth application (becon), uart etc. kindly help on this , if there is hex file which i can directly flash into my board for confirming Bluetooth operation working. This is very urgent for us to get it done before CES2025.

Thanks

    Hello Ashok,

    Please have a look at this thread:  nrf connect sd which I think may be relevant to your case. Does your board include the optional 32K crystal? If not, it's important that you change the LF clock source to use the internal RC oscillator by adding this line: "CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y" to your project configuration file (prj.conf). Otherwise, the program will enter an endless loop on startup waiting for the crystal oscillator to ramp up.

    Best regards,
