如果找到一个设备，我连接到它，然后写入特征。
我的问题是:
每次我尝试写外设，状态是3 (att_error_write_not_allowed)在write - completed事件。
当我尝试用我的手机通过nRF连接应用程序，我可以读写没有任何问题。我用Raspberry Pi、我的手机和Dialog 14680作为外设试过了。
每次状态为3时。

 printf("start write\r\n");Uint16_t * mtu = 0;ble_gattc_get_mtu (evt→conn_idx、mtu);printf("MTU Rate: %u\r\n"， * MTU);Uint8_t test = 0x00; printf("uuid: %s\r\n",format_uuid(&charact[0].uuid)); printf("write\r\n"); ble_gattc_write(evt->conn_idx, charact[0].handle ,false , sizeof(test) ,&test);

charact[0] contains the handler from the Characteristic.

Many thanks for the effort in advance.

Best Regards

HDR
