How to run "Nordic Thingy: 52" Demo on nrf52832 (pca10040) board?

Dear all

I am on the pca10040 board (nrf52832), and I see the "Thingy_bridge" program is pca20020 board, as shown in Figure 1;

I am in the burning process, the simulation is always wrong, as shown in Figure 2, I do not know what caused the Yes, please help me

Hi,

In your image you can see that you get an error at line 209 in drv_ext_gpio.c. If you look it up you can see that it is the function called drv_sx1509_reset() that returns the error. If you dig further you can see that this function tries to reset the sx1509 by writing a few command bytes to it using TWI. So my guess is that you haven't connected an sx1509 to your PCA10040 causing the TWI write operation to fail and return an error.

Hi MartinBL

Thank you

I found the pca20020 board contains a lot of sensors, such as temperature, humidity, pressure, control quality, color, etc., but now I do not need all sensors, How do I modify the relevant function inside the Demo? Can make my pca10040 board can burn Thingy Demo
Note: The pca10040 development board is not connected to the sensor

Best regards,

You will need to go through the code and comment out/delete the code that initializes and uses the sensors.

Hi MartinBL

Thank you. Now I commented on the peripheral program. I can use the phone to connect the development board control LED via Bluetooth. However, how do I need to make "Thingy_bridge" communicate with "Thingy_node"? I want to see all the node's battery level on the phone. I do not know which function to modify?

Best regards,

Have you followed the tutorial here? Where are you stuck?

Dear  MartinBL

I have already learned that linked tutorial. What I have encountered now is that after I burn the program, bridge(1) and node(3) are not connected. I don't know where the error is. I want to send the battery power of the three nodes to the bridge, and the battery power of the three nodes is displayed in the value of "UART Service". Please teach me what to do

[MartinBL]

Can you describe in detail how you are trying to connect the devices and when/how it goes wrong?

Do you get any sort of logging information out of the bridge and node?
