HI,
The nordic MCU I am using is NRF52832.
I am flashing the example code ble_app_uart which is coming in the directory "nRF5_SDK_15.0.0_a53641a\examples\ble_peripheral\" as part of the SDK example code.
When starting, I got build issue due to redeclaration of putchar() which I resolved by changing FILE * in int __putchar(int ch, FILE * p_file) to int __putchar(int ch, __printf_tag_ptr p_file).
After this, when I compiled and executed the code, I was succesfuly able to see two custom characteristics. And when I connected to the NRF device from nrfConnect app using BLE, I couldnt
see any prints in the TeraTerm application (in the COM port corresponding to the NRF device).
I tried to hardcode some data and send it to nrfConnect app using the function ble_nus_data_send(), but I was getting INVALID_STATE_ERROR.
I tried the steps in this link also
NRF_ERROR_INVALID_STATE when calling ble_nus_data_send after connection is established (https://devzone.nordicsemi.com/f/nordic-q-a/42244/nrf_error_invalid_state-when-calling-ble_nus_data_send-after-connection-is-established/164647#164647).
But I couldnt see any prints corresponding to check whether notifications are enabled or not.
Kindly help in resolving this issue.
