Wi-sun cloud gateway

R.Manu — Tue, 11 Jun 2024 13:36:17 GMT

For smart metering development using Wi-SUN communication, if the sensors are linked to a Leaf/Router within the network and the sensor data is relayed from Leaf/Router to Border, the data at the Border needs to be transferred to the cloud. Kindly recommend Wi-SUN compatible gateway recommended to gather data from the FAN and upload it to the cloud server?

Thanks

UART COMMUNICATION

R.Manu — Fri, 02 Feb 2024 13:00:19 GMT

Hi,

When trying to communicate with BP359C & BP35C5-T01 via UART from STM32F103RCT6 with Echo mode off. When query is sent a response is received, but when "Ip 2001:db8::26" is sent to change the IP address a response is not received.

Thanks

Hi,

Trying to connect BP35C5-T01 Wi-SUN module to PC but the driver is not installing automatically, tried to install manually from the website https://www.ftdichip.com/FTDrivers.htm but still unable to connect the device.I am using windows 7 (64-bit) virtual machine. Can you help me with installation of the driver??

Thank you

Hi Neil...

Is there specific size/method for UDP and TCP data transmission because I can send and receive 0123456789 and abcdef but unable to send other data like revanth(TCP) and 54211(UDP)

Thanks & Regards

BP35C5 Wi-SUN module

R.Manu — Mon, 03 Jul 2023 10:49:07 GMT

Hey!

What is the maximum distance two module(BP35C5-T01) to communicate with each other.

Also the connecting time for N number of nodes connected serially is

Minimum 33(sec) × N(node)
Average 70(sec) × N(node)
Maximum 177(sec) × N(node)

Suppose if we connect 50 modules it will take 3500 seconds (Approx. 59 minutes).

Does it take 59 minutes actually? Because 59 minutes to connect is very long...

Thanks & Regards

BP35C5 Wi-SUN module by ROHM semiconduction

Hey there!

I have been using BP35C5-T01 evaluation board along with BP359C evaluation board, for serial communication. The BP35C5-T01 evaluation board has two SMA connectors, to connect the antenna's. let me know if i can establish communication between modules without connecting antenna's. Also let me konw if i can establish communication between modules by connecting only one antenna.

Thanks...

BH1715 light sensor problem

Former Member — Fri, 05 Oct 2012 09:30:11 GMT

Dear Guys,

We had some trouble with BH1715FVC (Farnell ID: 1716295).

We have mounted some ten pieces of these ICs, and almost half of them work wrong. It means we cannot communicate with them through the I2C bus. The real reason could not be recongized, but they just doesn't operate. After we change the device to another in the same PCB, usually solve the problem witch means the soundness of the printed board. Do you have any idea? I am wondering if we do something whrong. I solder them by hand at about 320 C... I know it is over the required temperature, but that value subjects to a reflow soldering, if I think well, and when I heat the pins at 320 C, it could mean about 250...280 C inside the package.

Also interesting that two devices had been operating properly for a week when once broke down without suffering any physical or electrical (presumably) harm. There were some lightening near the two sensors (some 100 meters)... maybe it could be the problem (could it be?), and it means a totally different situation. First I would like to have some idea about the problem I mentioned upper.

Thank you!

Adam
