Hello community,

I’m using the WLR089 module on a self-made PCB (just fitted) although I’m having difficulties in understanding how to program the module (no debugger).

I've downloaded the "SAM R34 MLS Getting Started Guide" but the  Bootloader PC Tool Usage paragraph (5.5.1) refers to the SAM R34 Xplained Pro evaluation board.

The idea is to initially test the module capability by flashing the example code provided on the chip page (https://www.microchip.com/wwwpro...) via PC app (Bootloader PC tool) and, later on, try to update the module via UART from another micro.

Can somebody help/point me in the right direction please?

 

Best regards

Luca

Hello again, I'm adding info while tiring to understand how to use this module.

After several endless attempts to talk with this module via UART, I've decided to double-check its flash content. 

Being a module that aims to reduce the time to market I was expecting it to come with a pre-loaded application/stack but apparently is not...

I've been able to read dev signature and target voltage and once I've read the flash content I've found it is empty (maybe because of some sort of code protection?). 

Is there someone how has some experience with this module and point me to the right page/guide in order to understand what code needs to be loaded and how to configure/talk to this module?

regards   

 

############ update 2 

Projects are on git but they are for evaluation boards therefore a new custom_board.h needs to be created and all the extra component (LED, buttons, etc) needs to be removed from the code.

I'm now able to talk with the module via UART (no help received in order to understand if I can update the module over UART).

Playing with the module and learning about the Microchip Lora stack (MLS- SAM R34-R35 Microchip LoRaWAN Stack Software API Reference Manual ) I've noticed that the documentation is old and lots of LoRaWAN/MAC Attributes are missing (see typedef enum _LorawanAttributes into the lorawan.h file ). 

Has Microchip any intention to keep supporting this product and updating their documentation?

 

regards

Hi,

please help needed.. I am having the same experience with you... I want to use the WLR089 on a custom board but I can not communicate with the module as if it is not running.

Did you finally understood if the module comes with firmware preloaded?

Did you have to program the module with a debugger or you managed over the UART?

 

Thanks

The WLR090U0 Module is designed specifically for use with the WLR098XE-LF-10 Series Power Supply and is compatible with the following products: WLR098XELF-S5-10/12/15/20/25/30/40/50. This module can be used to power any combination of LEDs with current ratings from 4A to 30A. The U0 model is equipped with a 10A fuse, a reset button, power input protection circuit, and LED indicators for both over current and short circuits. Seeing 444

1. Module Description
 The WLR089U0 module is used to control light intensity and power consumption for various applications such as monitoring and controlling indoor grows, hydroponic systems, and other similar uses. This product works with low-power lighting technology using LED lighting that are designed specifically for this type of application. The unit features a built-in sensor to measure and report the ambient light level and an adjustable current limiting circuit to prevent voltage fluctuations from causing the lights to flicker. A temperature sensor provides accurate readings for use in heating and cooling environments.
 2. MLS Applications
 This device can be applied in many different settings. In addition to being used in greenhouse, hydroponics, and indoor garden applications, they can easily be integrated into automatic irrigation systems, HVAC units, and heat pumps to provide efficient energy savings.
 3. How Does the MLS Work?
 When combined with a solar panel (and batteries), the MLS can automatically regulate the amount of power supplied to both the lights and the power supply components, allowing them to operate at their optimal performance and save energy in the process.
