rssi viewer with different uart pin

[June20]

hello,

I'm trying to use RSSI Viewer for my custom board - problem is I need to change UART pin.

How do I make my own FW/binary for RSSI viewer?

My custom board uses nRF52833.

I tried to use Segger Studio and just tried to build https://github.com/NordicSemiconductor/pc-nrfconnect-rssi rssi_cdc_acm

The code seems like it is for Keil Studio, I don't know how to configure it to build it properly.

I did get as far using usbd_ble_uart_pca10056 _s140 because it has 'usbd' but got error: 

Output/Release/Obj/usbd_ble_uart_pca10056_s140/nrf_dfu_trigger_usb.o:(.rodata.m_app_dfu+0x4): undefined reference to `app_usbd_nrf_dfu_trigger_class_methods'

My guess is flash_placement.xml need modification - I don't know how.

Is there easier way to build my own binary for RSSI Viewer for my custom board?

If I can build it using Segger Studio, what are the configs, etc, and etc??

Thanks in advance

I will be away for about 3 days.

trivial, I have nrf52840dk, nrf52833dk. SDK 17.1.0 and S140

(also custom board has been connected to modified nrf52833dk)

Hi, 

It should be able to program the nRF53833DK by the RSSI app. Can you try that?

We don't have the project as your requirement, but you could use NCS and the Bluetooth shell which has a scan feature for Bluetooth devices, this includes RSSI values in the scan result. Have a look at this example Bluetooth: Observer

Hello,

Yes, we did get nRF52833DK to work, it just that our customized-nRF52833DK didn't (it did work, it just that due to modified UART pins we couldn't get any information).

In pc-nrfconnect-rssi/fw/src there are two main: rssi_cdc_acm and rssi_uart, what does each represent?

About the Bluetooth: Observer, do you have other version for SDK17/segger studio? I am not familiar with sdk-zephyr.

Thanks

CDC ACM is for the 52840 dongle since that is the serial port emulated by the USB stack running on the nordic chip. UART is for the serialport from JLink.

Unfortunately, no. Only the NCS. You can take a look at NCS Getting started guide.

I got it worked!!

nrf52833(pin modified) and nrf52840!

SDK17.1 S140

put it in sdk/example/peripheral

tell RSSI Viewer no and just wait till it works

no promise though

z_rssi_build2.zip

EDITS: you might want to modify nrf_drv_uart.c and nrf_drv_uart.h

Happy to know you make it work and thanks for the sharing.
