Other Parts Discussed in Thread: WL1837, WL1835,

Tool/software:

Hello,

How to identify the which chipset is connected on Hardware board. Please suggest the way which is differentiate between the WL1837 and WL1835 modue.

Regards,

    Hi Shailesh, 

    The modules should be labelled with the corresponding part number. Here is the device marking for WL1837MOD, taken from datasheet:

    And here is WL1837MOD:

    If you're asking on how to do it from software: The WL1837 has 5GHz enabled. So perhaps you can issue a Wi-Fi scan, and if you see any 5GHz APs in the area, then you can know that is a 1837 device.

    Hi,

    Thanks for the update. Is it possible to differentiate between the WL1835 and WL1837 modules at the software level during initialization? This would be ideal because currently, we control Bluetooth range through the application for the WL1835. However, the WL1837 with 5GHz support requires fine-tuning existing power gain settings for optimal range. By having a software differentiation mechanism, the application could load the appropriate Bluetooth power gain based on the detected module, allowing for seamless range control across both modules.

    Hi Shailesh,

    Unfortunately we dont offer any part number detection for either of the modules. My suggestion would be to instead find the gain settings you require on the WL1837 and then apply them for both, if possible.
