NRF52832 stops scanning when trying to send data to ESP8266 through UART.

[kishor babu]

I am working on a project where I need  to transfer the data from nRF52832 to ESP8266 through UART. I made the connections RX to TX and TX to RX.

I am using ble_app_uart_c centrl, sdk 11. Here the central is not connected to any peripheral, it is just scanning data from beacons and the scanned data I want to send it to the ESP8266 through UART.

I am using tera term for observing nRF52 data and serial terminal for ESP8266. Initially few bytes of data is transferred from nRF52 to ESP, within a fraction of time nRF is stopping the scanning and no data is transferred.

I checked by closing the teraterm, but at that time nRF is scanning but not sending any data to ESP. When I open the teraterm again it sends a few bytes of data and stops scanning immediately. 

Could anybody help me in solving this.

I'm not sure what you mean by that - please post a diagram showing how you have the nRF52832 connected to the ESP8266, and how the two terminals are connected.

What do you mean by, "serial terminal" here?

How, exactly, did you do that check?

Again, a diagram would help.

Have you used the debugger to see what's actually happening inside the nRF ?

Hi Awneil,

Thanks for the reply, I was able to solve the issue by debugging.
