CC-6lowpan-dk-868 Nodeview

Hi,

You need to change the Rf configuration on both the nodes (CC1180DB and CC430xx) and the Edge Router/Access point, and they need to match. You cannot change only the Edge Router and not the nodes, it will result in the beahviour you see. In short (example for CC1180):

1) On CC1180 you need to make the rf_config struct contain your settings:

//rf configurations to load...
static rf_conf_settings_t rf_config = {DATA_RATE_50, CHANNEL_SPACING_200, MODULATION_INDEX_10,
0x21, 0x65, 0x6a, 0xc2, RX_ATTENUATION_0dbm, FHSS_DISABLED};
rf_conf_set_params(&rf_config);

2) Build and download the new code to the MSP430 on the CC1180DB

3) Make the same RF changes on the Edge Router using NodeView tool.

The steps are described on p.28 in section 3.6.2 and 3.6.3 in the User's Guide for the CC-6LOWPAN-DK-868

The default settings are:

Data rate=200
Channel spacing=200
Modulation index=1.0
Base frequency=868.3MHz
TX power=10dBm
RX attenuation=0
Freq. hopping=0

Hi. Thank you for your answer.

I already changed frequency of CC1180DB nodes. But Edge Router could not connect any nodes.

I tried both 868MHz and 915MHz on Edge Router using two deiifernt frequency nodes.

First, I tried one CC1180DB node has not changed anything. That case changed frequency on Edge Router 865MHz to 915MHz.

Second, I tried other CC1180DB node has chaged frequency. That case also changed frequency on Edge Router 865MHz to 915MHz.

But both case did not work.

I think node frequency is not problem.

Hi,

Note that the default frequency is not 865MHz, but 868.3MHz. The screenshot in the User's Guide is wrong.

Please verify RF configuration used on CC1180DB and Edge Router by:

1) Simply copy the struct you use on CC1180DB and send to me

2) Log in to the Edge Router and do a cat of the rf_configuration_x file like below:

root@da850-omapl138-evm:~/last/configFiles# cat rf_configuration_ttyS1.conf
Interface Id=0
Crystal=26
Data rate=200
Channel spacing=200
Modulation index=10
Base frequency=2188650
TX power=194
RX attenuation=0
Freq. hopping=0
root@da850-omapl138-evm:~/last/configFiles#

Send to me for verification.

Thanks,

Jonas

Hi,

I solved that problem. The frequency on Edge Router was the provblem.

I changed frequency and data rate that you told, both 868.3MHz and 915MHz I confirmed connetion through NodeView.

And I have another problem.

I downloaded on CC1180DB success, but I failed on CC430F5137.

The error message I attached.

Help me again.

Thank you. 

Hi,

Ok, good you solved it. 

I have not seen this error before, please describe exactly what steps you took to invoke it. Be as precise as possible.

Thanks,

Jonas

Hi, again.

First, I sloved that problem, I changed JP2 pin INT to EXT on CC430 board, then download worked. I don't know What do that pin is rule. Could you explain?

After all, I tested Edge Router on 915MHz using nodes(CC1180, CC430) well. But I had problem too.

A few hours ago, I worked well. After adapter board disconnected from Edge Router, I connected adapter board. But Edge Router did not boot.

I found similiar problem(http://e2e.ti.com/support/low_power_rf/f/155/t/208182.aspx) but there are not answer.

The LED D1, D2 both blinked period 4s.

I tried to connect using telnet and serial port. But any one did not connect.

And I found some thing on user guide. But I can not understand. How I can solve?

Thank you.

CC1180 stuck in boot mode

The CC1180 on the Gateway can sometimes get "stuck" in boot mode. This is due to ripple on the CC1180 MODE pin during boot of the Gateway (a falling edge on MODE line will toggle mode on CC1180). The utility Nanoboot_host can in such case not be used to toggle mode, this is due to the fact that the program requires the serial port to the CC1180 to be open and that fails under these circumstances. In order to toggle mode of CC1180 the MODE line can be controlled directly from Linux user space, to do so follow these instructions.

1. Assuming you target GPIO1_15 (MODE on CC1180), in linux it will be represented by gpio31. 2. In order to be able to control it, you need to make it available for control echo 31 >/sys/class/gpio/export 3. Then you can check its direction: input or output cat /sys/class/gpio/gpio31/direction 4. Assuming you want to set the I/O in output mode & toggle its value from 0 to 1, we need to change the direction first: echo out > /sys/class/gpio/gpio31/directionand then we can verify direction was changed cat /sys/class/gpio/gpio31/direction

(out should be displayed)

5. Then we check the value :cat /sys/class/gpio/gpio31/value

(that defaults 0)

6. To set to 1, echo 1 > /sys/class/gpio/gpio31/value

7. Since a falling edge on the MODE pin will toggle mode on CC1180 we need to set the signal low again:echo 0 > /sys/class/gpio/gpio31/value

8. And set it back high in order to be able to toggle it again later:echo 1 > /sys/class/gpio/gpio31/value

9. The mode of CC1180 is now toggled and is displayed on the LEDs on the adapter board.

10. If both the LEDs are toggling with about 5s cylce, then power on OMAP and let nanorouter start.

11. You can now create an RF interface as usual (not sure you need, depending on if you have one already) and connect your nodes.

//////////////////////////

Seems like your Nanorouter process is not started, you can start it manually by using the console interface on the Edge Router (RS-232 or telnet):

(standing in root)

cd last [enter]

./nanorouter [enter]

You will now also get debug from nanorouter application on the console, if that's not desired use ./nanorouter & [enter] instead

Jonas

Hi.

I did what you said.

cd last

./nanorouter

but the script did not stop.

How it unthread boot mode?
