BLE Receive problem

Hi everyone,

I searched the forum and still can’t find an answer. I have no problems sending data to my BLE device. I can make everything that I want on my project. But receiving is the problem…

I can’t receive any data from my BLE device. Nothing is working. I have seen a lot of topics on the forum but the problem still there. Has anyone a solution?

Thanks for your time!

Hey @fjrubiotorres962q

What BLE device are you using?

What format are you transmitting the data in?

Yes, I have the same problem, I use hm-10/jdy-08. I send integer number every 150 milliseconds, but at label I see only “null” if do “get object from JSON”. Without “get object from JSON” nothing happens.

What is the full JSON response that you are getting?

If an error is output, it is output that the operation was rejected. If you output data(string), null is displayed

I read similar topics in the community, but no one has yet solved this problem for these modules. Everyone believes that the problem is that the chip that underlies the cc2541 has only one characteristic UUID for TX/RX (0000ffe1-0000-1000-8000-00805f9b34fb)
