      • CP2201 problem at low temperature

        We use your CP2201 ethernet controller in our design and we have a problem with working on the low temperature.
        According to oscillogram, the RST signal (RST# pin) rises to high state at least 20 sec after the power (+3.3V) has been started.
        We don't use external control for this signal during that test. We noticed that the time between start of +3.3V and rising of RST is approximately 20 sec at -15C,
        40 sec at -30C and 2 min at -45C. Could you help us with that problem?

      • MCU with WT32i

        How do I use an external MCU to execute commands on the WT32i?

        How do I get the address of a paired unit off of the WT32i?

        I need to use a button to put the WT32i into a pairing state which pairs to the closest other bluetooth unit that is also in pairing mode.

        For this I need to get nearby bluetooth units addresses and CoD codes. How do I request this off of the WT32i?

        How do I tell the WT32i to pair with (X) address once I get the list of closest addresses?

        One of the bluetooth headsets I am using throws the RFC_CONNECTION_KEY_MISSING when I try to call it on a HSP profile. The datasheet is extremely unspecific on what these error codes mean or lead to or how to stop them from occuring.

         

        Some basic examples for how to accomplish communicating commands from an MCU to the WT32i will be appreciated!

         

        Thanks.

        Hi 

        We are developing communication box having FXO interface . This interface is connected to Local PBX (Intercom within premises) .   We plan  to use either Si32178 or Si32179 . We are searching for reference design board ( evaluation board ) for these chips?  We are looking for programming help  over SPI interface .Pl share the documents link where we can get program details ?

      • SD Card write in SPI mode fails after some time.

        In our device, we have a sensor generating data at 250 sps and we get around 5K data from the sensor per second. We want to store this data into micro SD card through SPI. We are using SPI at 8MHZ.

        We are able to initialize the card and write to it. But when we try to write for a long duration, the write fails at some time. And the card response to write request is 01 i.e Card in IDLE_STATE. We get the same problem with different cards.

        If we power cycle the board, the write succeeds from the last failed location. We are doing a raw data write directly to the sectors. No file system is added due to memory problems. Also we can write only single block at a time again due to memory problems.

        Can anyone suggest us how to solve this problem please?

         

        Thank you,

        Bharath

      • how to achieve the bind between the Z3GateWayHost and Z3SwitchSoc 

        Hi 

        Zigbee 3.0 , EmberZNet 6.0.0.0 ,Chip: EFR32MG1P232F256GM48.

        I need to implement the function that Press the button on Switch to control the LED on/off on GateWay based on the Z3SwitchSoc and Z3GateWayHost example.

        Now i achieve that the GateWay can achieve some information which is sent by switch ,but the function is implemented by CLI command "  binding-table set " .

        So i want to use the code to achieve this function . And then i add the " Find and Bind Target  " plugin into the GateWay project, but failed.

        So i want to know how to achieve the bind between the Z3GateWayHost and Z3SwitchSoc 

        Thanks

      • Unicast multiple short data packet loss problem!

        Hi SiLabs, Experts,

        I now have a problem, I have a coo linked below 25 routing equipment, I need to send transparent data control these 25 devices, you can use multicast (all devices can receive commands), but also unicast Control, my approach is to send these instructions for the loop, and the return status also shows that the success of the transmission, but there are always about 5 devices are not controlled successfully (can not receive the command), which is why? Hair too fast congestion it? We also made a reissue, but some of the devices failed to control (to make sure nwk was correct, I tried to send commands to this device constantly, to control the success of the 27th), which is why ah?

        Thanks in advance!
