Newt target show. In your case it's my_blinky_sim. I can tell because it's in the path to the elf file-- every target's build is put in a separate directory. Sterling > On May 28, 2016, at 6:05 PM, David Moshal wrote: > > how do I find the name of the target? > Dave >

I agree - it should just default to 0 imo. When I run on real targets I usually just provide 0.0.0. Failing a default, it should work consistently and display an error when you don't provide a version. Sterling > On May 28, 2016, at 3:48 PM, Christopher Collins

Re: Correct way to add a task that only runs once

Hi James, Callouts are perfect for this type of function. I’d recommend multiplexing this within the task context you are running out of. Essentially the logic works like: - Turn the LED on - Set a callout for 1 second to turn the LED back off If your task is waiting on an event queue,

Correct way to add a task that only runs once

Hi, I want to be able to flash an LED on for ~1 second when some condition occurs. I don't want this to be flashing all the time like the blinky example. What's the right way to add a task that runs only once? Or should I not be using a task at all for this? Cheers James

How to determine the length of received data in a GATT callback

Hi, Looking at the peripheral callback gatt_svr_chr_access_gatt, is there a way to determine the length of data received? Here's the whole function definition. static int gatt_svr_chr_access_gatt(uint16_t conn_handle, uint16_t attr_handle, uint8_t op, union

David, Sterling, let me throw in my 2 cents. Firstly, Thank you David Simmons, it's really interesting to look at it from the perspective of the original embedded Java efforts. I recall following that project closely in the late 1990s. In the case of Javascript though, I think the problem may be
