I²C sensor data transfer over BLE

domsn99

(Protocol of my I²C Device)

I have tried the nRF52832 DK for a while now with the examples and so. I want to program a different Bluetooth Module, the EYSHSNZWZ from Taiyo Yuden.

I have tried the examples on the new module and they kind of worked but I had difficulties with bonding devices after I turned bluettoth on my Smartphone on and off. I thinks it's a problem in the device manager. Didn't figure it out yet.

Finding out the hard way that simple copy paste won't work out for my project I am now trying to adjust the services and functions for my purposes. 

My question is how I can realize it and which parameters I have to change to get the results I want and maybe solve the problem with the device manager.

    Hi,

    1. Is there a specific reason you believe it is related to device manager? 
    2. You say "difficulties", did it work at all or just sometimes?
    3. Does I2C have anything to do with this?
    4. Did you base you application on a specific example in the SDK? What changes have you made?
    5. Can you describe your use case in more details?

    Hi,

    1. When I try to bond with the device it says that the module denied the bonding. I have read some forum posts and I thought it could be the device manager.

    2. When I delete the whole RAM of the device, build an example solution and try to bond, it works. If I delete the bonding informations, problem 1. appears. As long as I don't turn off bluetooth from my phone or reset the module, it stays bonded even if I power off and on the module.

    3. I only mentioned I²C because the protocol of my I²C device is different from the temperature sensor of the nRF DK and wanted to know how I can change it.

    4. I tried the hrs and twi example, but I want to merge both functions.

    5. It's a project where I want to read out data from sensors with I²C and process them with the module. I have a smartphone app which sends a request to read out the register where I store the results from the sensors.
