Re: How do you program something like this?

For the Ehong module you will need the: EH-MEVK-MC10-002 is the development evaluation board, providing the complete interface features of EH-MC10. The Quick Start Guide guides you to launch and run the modules within minutes to test and evaluate the modules' performance. You will also need the SDK...

Re: How do you program something like this?

Some Bluetooth (or WiFi or ZigBee) modules are not intended to be user-programmed; they come preprogrammed with a processor that has a serial interface of some sort, and only intend you to use it as a peripheral. The one you mentioned is in this category. Others (ie. ones based on the Nordic or Sil...

Re: How do you program something like this?

Why would you want to program the board? Microprocessors found on boards like that are often programmable only one time (OTP). I'd like to know how to program the board because it would allow for just that one board to handle all bluetooth plus logic involved for a project so I wouldnt have to use ...

How do you program something like this?

I'm wondering how you program a board like like:

https://www.sparkfun.com/products/14839

It seems like there's a microcontroller embedded on the board which you're able to program somehow, but how do you do that?

Re: Can this be used as I2C Master?

In this case the Bluetooth is a slave and I2C (instead of the UART) is used by a processor to send and receive Bluetooth transmissions. You also need a processor to read a sensor, format and send the data to the Bluetooth module. Got it, thank you! So it doesn't seem like there's any options for a ...

Can this be used as I2C Master?

I'm starting to learn about I2C, and as I understand it there needs to be a master involved in the chain to provide the clock signal. I wanted to know, can this bluetooth module be used as a master device? https://www.sparkfun.com/products/14840 My thought is to connect other sensors to it and trans...

Re: From prototype to production?

You learn new techiques. Hand soldering doesn't work well below 1206 parts or 0.5mm lead spacing. Below that you need to use paste and reflow. It's so much faster, I never make through-hole boards anymore! It's really not hard, although I personally don't go below 0603 parts. You need to do a PC bo...

Re: From prototype to production?

Generally speaking, prototype with the parts you expect to use in production unless there's good reason not to. I think what you are describing can be better described as a "proof of concept" than a prototype. Thats a good point, you're right, thank you for that distinction! However, if I do prove ...

From prototype to production?

Hey guys, So I'm experienced at a hobbyist level of building things, plugging components into a breadboard and programming microcontrollers. However, my question now is, after I've bought some stuff from Sparkfun or wherever and have a thing that works, where do you even begin to take it and make a ...

Re: Garage door sensor using Xbee (apartment complex)

Unlikely any of the 2.4GHz ones will work with this much non-line-of-sight at 500ft. Yeah I was thinking that too. But what about the Xbee Pro 900? I see that it can have a range up to 15 miles, so I would think it would have enough juice to get through the concrete, right? I'm just not sure how di...

Re: Garage door sensor using Xbee (apartment complex)

re "There are lots of obstructions between his apartment and garage." you'll have to be specific on this - it's an RF world. Obstructions as in the building the garage is attached to and his building itself. I know the Xbee has good line of sight distance but I wasn't sure which one would work with...

Garage door sensor using Xbee (apartment complex)

One of my friends lives in an apartment complex and has a garage, however its attached to a separate building (Lets estimate around 500 ft). I want to build a garage door sensor, using Xbee's and a reed switch, that will let him know when the door has been opened/closed (it will communicate with ano...
