Original question:

WL1837MOD: CONTINUOUS WAVE MODE SETTINGS

WL1837MOD: CW setting and Communication distance

Takayuki Miyazaki
Genius 10120 points
Part Number: WL1837MOD
Other Parts Discussed in Thread: AM3356, , WL1837

Hello Experts,

My customer is developing their system with WL1837MOD/AM3356. Since customer had the proto-type board, they would like to check WiFI-Tx Continuous output power（2.4GHz/5GHz）and BT Output power with their board. As far as I checked, I found the following helpful URLs.

https://processors.wiki.ti.com/index.php/WL18xx_TX_Testing#TX_Tone_Test for WLAN

https://processors.wiki.ti.com/index.php/WL18xx_Bluetopia_PM_Bluetooth_RF_Testing#Continuous_TX for BT/BLE

would you think those URLs are still available ? if not so, could you share helpful URL for them, please?

 

Also, customer would like to check the communication distance（2.4GHz/5GHz）with their board by simple way.

I believe Demo procedure is easy way. Can I have your Expert's advice/comments on this, please

https://processors.wiki.ti.com/index.php/WiLink8_WLAN_Demo:_Linux

https://processors.wiki.ti.com/index.php/WiLink8_WLAN_Advanced_Demos:_Linux

Regarding BT, I'm not sure what demo is helpful for customer.

https://processors.wiki.ti.com/index.php/TI_Bluetooth_Stack_for_WL18xx_-_Demo_Guide

it will be appreciated if you will share Expert's advice/comments.

Best regards,

Miyazaki

    Hi Miyazaki-san,

    Yes those wiki's are still valid.  They will be removed by the end of the year, so we are looking to migrate those to documents hosted on ti.com later this year.

    I'll ask other experts to chime in on SW demos.

    Regards,

    Travis

    Hi Miyazaki-san,

    As Travis mentioned those wiki documents are currently still useful for the WL183x products and RF testing links show how you should test the RF capability.

    With the RF testing guide you should be able to perform the needed measurements for output power to determine range, but if you wanted to check the range through a more hands-on experimental approach you can use some of the demos provided in the SDK.

    For Wi-Fi, the links you have are correct. I advise you use the script to connect to an AP in STA mode (or start  the device in AP mode if that is the customer's use case), and then run a simple Linux networking program to connect to a remote server to check the usable range.

    For Bluetooth, you can run the demo corresponding to the customer's desired profiles and then experimentally check the range that way. If the customer just wants a quick test, running the SPP demo and then running a phone app such as "Bluetooth Terminal HC-05" to connect to the WL183x device would work. There are instructions on the SPP demo wiki page that walk you through how to use that demo: https://processors.wiki.ti.com/index.php/WL18xx_TI_Bluetooth_Stack_SPPM_Demo_App

    Let me know if you need more clarification on the demos, or if you have further questions on performing testing on the WL1837.

    Regards,

    Michael
