I am currently doing a simple test to receive data from HM-10. However, it can not be received well and the characters of the received data will be garbled. The RN4020 BLE module can receive data without garbled characters. Please help me!🤣 ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/f/7/f757f69f765ac9baa9917d16e53e0e677960e70e.jpeg) ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/5/4/54e54d43019cdaacb08c72877c2e788a3c84cb7e.png) ---

Thank you very much! I can transmit without any problems in the tests I’ve done until now. I can not receive from the HM-10 BLE module. I tested it on Thunkable Classic to try it, but I was able to receive it. In Thunkable X I do not know how to do it. ---

Do you consistently get the same “garbled” response? Because it may not be garbled, it may simply be differently interpreted, by regrouping data to form multi-byte unicode characters. Try sending the NUMBER 12345 instead of a “12345” text string. ---

When transmitting from “Thunkable X” to “HM-10”, text strings can be received with “HM-10”. When sending from “HM-10” to “Thunkable X” I always receive the same garbled reply. I tried to transmit numbers from “HM-10” instead of text strings, but the result did not change. Thank you for the advice. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/6/a/6a8a5ecea915ca6ecf4671fad29d8e7c2a2900a4.png) ---

Another thing perhaps worth checking. I notice that your receiving block is in a “Timer” block. What is controlling the firing of that timer? Is it firing continuously? And what is the millisecond interval setting? I am wondering if you are not receiving _again_ AFTER the original, even when there is nothing transmitted anymore. ---

The timer has an interval of 500 ms. I need to constantly monitor the incoming data from “HM-10”. I also tried to receive when I pressed the button I thought the timer was a problem, but it was the same. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/3/7/371b471a514f8487ae4e7b79a51bbb49b73757ae.png) ---

If you do the same thing with Microchip RN4020, I can receive the expected string normally. It may be a problem specific to HM-10. However, there is a question that “Thunkable Classic” can receive but “Thunkable X” can not receive. I will investigate further.

I have the same problem with the HM10 module. It sends ok, but doesn’t receive. I have tried a COUPLE of things, but still doesn’t work. Thunkable X app doesn’t receive at all. Here’s a link to my project: [https://x.thunkable.com/projects/5d7ecfd3383d27e29c8dde2b/b3231b63-7d98-4d05-a8b0-837f4ec8160b/blocks](https://x.thunkable.com/projects/5d7ecfd3383d27e29c8dde2b/b3231b63-7d98-4d05-a8b0-837f4ec8160b/blocks) ---

hello, same problem here BLE on x-app won’t receive at all ---

Similar problem for me. I get this error in output for the BLE component: > can’t read the characteristic provided I connect via `device name` then use `Characteristic UUID` to receive info via `Call Receive`. The info is `float 4 byte`: like 25.000000. When I try to set data my app receives to a label I get `undefined`. @domhnallohanlon Any ideas what is wrong? UPD: My problem is related to Thunkable: it converts a `float` or an `integer` it receives to a `string`. In my case sending `integer` 50 is received as `string` “2” at Thunkable app. ---

Same Problem with nRF52832. I receive garbled data when using receive string but when I change it to receive byte array I get the below error: n is not a function. (In ‘n(void 0,I.t0.message)’,'n’in undefined my data is in hex format so I should use byte array but I don’t know how to fix the error.
