The esp8266 boards are close to each other so signal strength should not be an issue.
1] I am getting a large number of udp packets that are not being transmitted(90%). I am sending a packet every 300mS.
This is verified by what is received by the second esp8266 and also via a monitoring app on an ipad.
2) I do not get a call back when the packets are sent despite registering the callback. The receive callback does function.
Please can you advise if this is a bug in the RTOS firmware that I am using.
If not, can you advise how to debug this.
I have included the printout from the bootup sequence which shows the firmware and hardware versions.

2. Maybe you can try with the latest version of RTOS. https://github.com/espressif/ESP8266_RT ... ls/sockets
