Case 1. Obsolete Wi-Fi module replacement

case1

Client:    manufacturer of solar energy devices.

The gateway device:

collect, process, and display information from an array of solar panels. The RS9110-N-11-24-02 radio module was used for communication, which provides communication over Wi-Fi of the 802.11 b standard. On the microcontroller side, the lwIP library was deployed to implement the TCP/UDP network layer and the IP protocol layer.

An issue:

The solution contained shortcomings: network stability problems caused by porting the cumbersome lwIP library to NXP processors, and a long loading time, since the communication module required initialization before each launch, which also complicated the architecture and startup sequence of the entire device. But the solution was generally viable and worked until the RS9110 modules were discontinued.

Solution:

switching to the Wi-Fi module ESP WROOM32U (802.11 n), modified the client code so that the implementation of network protocols moved from the processor to the hardware of the new Wi-Fi module, more unnecessary network library was removed from the firmware of the microcontroller, memory and CPU load were freed, the architecture was simplified by independently loading the module from the static memory of ESP32.

Benefits:

Case 2. Adding a radio module for hardware-reborn to the old system

Client:    manufacturer of industrial washing machines.

The devices:

Huge arrange of commercial laundry machines of different series.

An issue:

In the series of machines developed over the years, various UART protocols were implemented to transmit data on the intensity of use, errors that occurred, and other statistics, but this data was collected manually: during the service process, the master connected wires to each machine and read the data.

Solution:

An expansion board with a NORDIC microcontroller and an nRF52 radio module were developed and manufactured. On the basis of the MCU, an interpreter of all existing UART protocols of all available series of machines was implemented; data through the radio module using the Thread network over the Ethernet channel began to go to the server hosted in the cloud. The customer added the developed expansion board to all existing machines and installs it in new ones. All the company’s devices are connected to a single network, and data is automatically collected in a single data center.
