I have BP device, It has start button. When we click the start button then it start monitoring the BP. Need to start/stop the device to monitoring the BP from the iOS App. Is there any way to achieve that?

Is it your device that you developing or just a 3rd party device ?

It just a third party device. It's Fora Bluetooth Smart Devices.

Then it doesn't have much to do with Nordic.

I hope you get help from someone here on this forum, but the chance is small.

Hi I got the doc from company, but unable to understand the doc. Can you help me out in sending cmd and acknowledgement?

2.2.5. [0x27] Read device serial number, part 1
Message Name: Read the device serial number, part 1 Message ID: 0x27 Message Description: Read the device serial number, part 1. This command cooperates with 0x28 to complete the serial number. Src / Des: GW / MD Length: Request: 8 bytes / Response: 8 bytes

What is the use of Message ID and how to send this cmd to device ?

I suggest you to direct your question to the vendor. It's really hard to know what to do with just the quote you send. There must be some explanation some where in their documentation on what the Message ID and how to send it.
