Problem : Not able to communicate between esp32 and thunderboard sense2 using ot-rcp .

Configuration :
1)Flashed thunderboard sense 2 with ot-rcp hex file(using simplicity studio)
2)Build ot-cli using following link : https://github.com/openthread/ot-esp32/ ... /README.md and flash the generated binary to esp32.
3)Connect pin no 12(uart tx) of thunderboard sense 2 to rx pin on esp32 and pin no 14(uart rx) of thunderboard sense 2 to tx pin of esp32.
4)Using 39a4915db205640e099a433944f3a715c253ca65 commit id for ot-esp32
5)Using 3b362071e594375035e063c0c25988b1aa52bd5f commit id for openthread.
6)Tried following configuration for ot-rcp on thunderboard sense 2
1)Gecko SDK Suite: OpenThread 1.1.2.0 (GitHub-5c2ad91cf), Platform
2)Gecko SDK Suite: Amazon, OpenThread 1.2.0.0 (GitHub-cf21d5760), Platform
4)Run the application on esp32 for both of the above mentioned configuration one by one. Got the same failure message on both of the case.
