无代码:过程of writing to a characteristic

Hi,

I am using codeless, to transfer data from peripheral to smart phone, by writing into characteristic. So, when I do ATrl+"String", the characteristic gets written with that string.
This is working nicely even for large strings like 240 bytes. Now, I want to use this to transmit image from peripheral to smartphone. For this, I broke down the image to bytes, and I am sending ATrl+240 bytes of the image in packets. This writes only a few characters into the ble characteristic.

My suspicion is that when codeless receives from UART, and writes to ble characteristic, it stops writing at a particular character, and unfortunately, the byte value of the image might just equal that character. So, random pieces are being written to the characteristic.

I checked whether it receives everything properly through UART, by echoing , and it echoed 240 characters, or rather bytes, but the characteristic only gets a few.

Can you look into this please?

Thanks
