product details:
nRF52840 custom board
nRFConnectSDK 2.2.0
we want to implement custom service interacting with the Android app.
Where we will receive on command from Android app and we will do some processing and sending the data back to the android app.
For this what and all we need to do.
for ex: service
what characteristics and what descriptors are needed and their properties.
All we need to know is how to write custom service and for our requirement what we need to add.
we have two different products where in 1 it goes as USB CDCACM.
In another we have UART interface. In this we want to tap the data to BLE connected to Android app/ios app. In the same we want UART communication to iMX.
Ofcourse currently testing this with laptop instead of iMX where UART driver send data to COM(testing with tera term). Final thing will be iMX.
Is this both possible in single application. Currently as you suggested we are in process to move UART method to serial recovery method. But before that making our code work with BLE over UART has become priority. So requesting this in paralllel to other ticket.
adding to the above query, UARTE is taking uart0 i think.
Just now found nelw lines from:
C:\ncs\v2.2.0\zephyr\modules\hal_nordic\nrfx\kconfig
So will uart0 is available for BLE and also COM/shell connection.
for shell/data communication we are using below"
#define UART_DEVICE_NODE DT_CHOSEN(zephyr_shell_uart)
struct device *uart_dev = DEVICE_DT_GET(UART_DEVICE_NODE);
Peripheral UART uses:
