• Bluetooth signal strength is greatly affected by human body intervention. You may check RSSI values, if the value goes beyond -90 dBm you may not have a reliable connection.

• You are right, my code is not able to catch any error or exception. addRouteAsync task was not succeed, i put the code under try and catch, did not get any error or data.

• MetaMotionR comes with nRF52 module, which is Bluetooth 5? if so then is there any increase in range and data transfer rate and volume?

• @Eric As you have written above, can you give an example in which case the battery can last for only 2 hours. Thanks

  in Button cell life with Metwear C Comment by rajmishra June 2017
• thanks. Li-ion can we attach to metawear C?   I experienced that Li-ion baterry doesnot last more than 6 months.

• Thanks Eric for all your support, I have attached 1 M ohm resistor, instead of my app i used to Metawear app to stream data. I am able to get data  from gpio pin continuously but after few impacts the board keep getting reset. I don't understand w…

  in Attach vibration sesor with RPRO Comment by rajmishra April 2017
• No did not, instead i used PULL_DOWN function as Matt suggested. gpio.initiateAnalogInRead(GPIO_PIN, Gpio.AnalogReadMode.ADC).pullDownPin(GPIO_PIN).commit(); here is the output logs, mostly after impact(on pressing the piezo surface) the value reac…

  in Attach vibration sesor with RPRO Comment by rajmishra April 2017
• By no change in data received means, that the data received is same with  PULL_DOWN and without. should there be any change ?

  in Attach vibration sesor with RPRO Comment by rajmishra April 2017
• @Eric The value of START_INTERVAL= 20 initially,after your reply I changed START_INTERVAL= 50, now getting data from piezo element and the board is also not resetting at even hard knock. @Matt yes it is essential to add a 1M ohm resistance as sug…

  in Attach vibration sesor with RPRO Comment by rajmishra April 2017
• Thanks Eric, The problem is solved, was using wrong value in GPIO_PIN variable. GPIO_PIN=1 solved the problem. If you could help me with another issue, since connection of vibration sensor to the board, the board gets disconnected rapidly within 2-3…

• thanks Eric, can you also suggest any particular type sensor which can go easily with preferably smaller.

  in Attach vibration sesor with RPRO Comment by rajmishra March 2017
• Eric, I configured with every possible combination but did not get any response at all. Could not detect tap even once.
