Hello,
I am applying Redboard Artemis example ble_freertos_amdtps using IAR , it works fine with nRF-Connect ,
i can connct the Redboard Artemis to it , and in debugging i have found out that there is a response when i ask for data in the file :
atta_ccc.c → in function : attsCccMainCback
but i really want to know, how to send data via BLE , even 1 Char
anyone has an idea ?
i used the code from https://github.com/paulvha/apollo3 in project ble_amdtp_arduino/Amdtps
and now i can use the incomming data( Mobile->Redboard_artemis) in the function AmdtpReceivePkt in the file amdtp_common 
but i still have to figure out how to send from board to Mobile :?:
bi-directional redboard nano to android 8.0 and higher. Has both android source and apk file. Board sends ack and echoes any command sent to it.
thank you for your reply,
actully i used your code and install the App , and give it all the promotions to access evrey thing it want , but i could not find any device when it scanns.
any way i used NRF-connect app and BLE Scanner App to connect the board , and i gut the same result
i can send data , but when i klick recieve i cannot see any encomming data
in UUID: …0012

uint8_t buf[4]={4,7,8,9};
amdtpsSendData(buf, 4);
