sd_ble_gattc_write and BLE_GATTC_EVT_WRITE_RSP problem

[Eddie]

Hi all

I'm trying to send 180 bytes using sd_ble_gattc_write(). Writing 20 bytes at a time with the BLE_GATT_OP_WRITE_REQ write_op works. But now I'm trying to speed things up by sending packets of 18 bytes each with BLE_GATT_OP_PREP_WRITE_REQ and then execute it with BLE_GATT_OP_EXEC_WRITE_REQ . sd_ble_gattc_write does not return with an error . But the BLE_GATTC_EVT_WRITE_RSP event returns with gatt_status 0x0182. Can't find out what 0x0182 means. Any idea?

	write_params.handle = m_nus_rx_char_handle;
	write_params.flags = 0;
	write_params.len = 18;
	write_params.p_value = m_txPtr;
	write_params.write_op = BLE_GATT_OP_PREP_WRITE_REQ;
	write_params.offset = current_offset; // 0 for first call

	err_code = sd_ble_gattc_write(m_adapter, m_connection_handle, &write_params);

Problem with the multiple writes is that there is only one packet of 20 bytes each connection interval. I was hoping to have 6 - 7 packets (of 18 bytes) each interval by using all buffers. Am I mistaken here?
