Hi.
currently i use the nrf connect with a dongle to connect to a ble device to read/write characteristics for testing purposes.
Now i want to do it automatically using...
Hi all,
I am adapting some examples according to my needs and have encountered something that I find strange. I am trying to send 244 bytes from computer to usbd_ble_uart...
I want to program my nRF52832 Over-the-Air but not through Bluetooth. We have a Wi-Fi chip interfaced with nRF52832 so that the device can be connected to the internet.
I am trying to read the current time using CTS. I used the example source provided by nordic. However BLE_GATTC_EVT_READ_RSP does not occur in ble_cts_c_on_ble_evt.
BLE_CTS_C_EVT_DISCOVERY_COMPLETE...
Are there any examples of sampling something like an I2C bus at a constant sample rate? I have seen issues myself with the k_sleep and k_busy_wait not giving accurate delays...
