Hi?? Samebody have the JDY-10 BLE BLUETOOTH 4.0 Datasheet and PINMAP? I Need localize the PIN RESET here to modify firmware
I hope this helps. I have yet to work with them if you find any good example codes send them my way lol 
This is the best I can get, I believe that the JDY-10 is very similar to the HM-10 cc2541.
I was going to upload a picture but it;s saying it's too big.
on mine the reset is pin #1.
for example if the bottom edge with all the pins is towards your body start from the top and go in a anti-clockwise motion for pin 1, 2, etc. I wish the picture had loaded. 
Hi Raptor, I'm currently working with this module, did you find out the purpose of pins 1-16? I'm interested to share information on the jdy-10, I'm only able to to use it as a slave.
Hi,
Has anyone got this module to submit data, aka "passthrough" mode? There's no AT+MODE command and no mode pin to pull low/high!
Regards,
Andrew
