customize the Nina AoA C2909 Nina TAG

[NCKGTW]

Dear Staff, 

we have some Ublox C2909 TAG based on your nRF52833 chip.We need to program them for an RTLS project.

In particular we need to:

• customize the FW here (u-blox/c209-aoa-tag: Bluetooth Direction Finding Tag sample application. Works with u-connectLocate.) by using VS code or similar
• the custom part is simple the following:
  • while the nrf52833 send AoA packets , it has also receive I2C packets (nrf52833 should be the slave)  from another I2C master

We have following doubts/information to ask :

1. how can we download the demo code (link above) by SWD and not by USB(UART) ? Which are the step to follow in Visual studio by using an external programmer?
2. do you have a demo app in which the nrf52833 or similar work like  an I2C slave in order to integrate it the demo app?
3. Is it possible for massive production , use a raspberry PI and OpenOCD to flash the FW on the nrf52833 chips without an external debugger in between them ? I see this tutorial that seem to work (Overview | Programming Microcontrollers using OpenOCD on a Raspberry Pi | Adafruit Learning System) , can you confirm? 

Hope you can help!

Thanks a lot.

If there is more than one external programmer or DK attached when you flash from VS code, you will be prompted which you want to choose when flashing.

do you have a demo app in which the nrf52833 or similar work like  an I2C slave in order to integrate it the demo app?

Look for overlay files using compatible = "nordic,nrf-twis"; An example can be:
\nrf\tests\benchmarks\i2c_endless\
\zephyr\tests\boards\nrf\i2c\i2c_slave\

Is it possible for massive production , use a raspberry PI and OpenOCD to flash the FW on the nrf52833 chips without an external debugger in between them ?

Our nrfjprog and nrfutil command line tools are using SEGGER J-link, so I typically recommend to check out production programmers from SEGGER. Other vendors may also exists, but not directly supported by us.
